- The document discusses the history and importance of preventive conservation, which focuses on controlling environmental conditions to slow the deterioration of collections, rather than treating individual objects.
- Preventive conservation provides more efficient use of resources over time by reducing the need for individual treatments. However, it can be difficult to implement due to the slow rate of deterioration being prevented and the lack of immediately visible results.
- The document outlines research conducted by the Getty Conservation Institute on identifying environmental threats to collections and developing cost-effective control methods through studies of pollutants, pests, and microclimates. Proper building maintenance and material selection can also support preventive conservation.
This document discusses various aspects of digital preservation for 21st century library collections. It defines digital preservation as ensuring long-term access to digital objects and describes common strategies like migration, emulation, encapsulation, and technology preservation. The document also outlines important considerations for digital preservation like file formats, storage media longevity, and the challenges of technological obsolescence.
The National Museum of Ireland adopted a conservation policy in November 2005 to preserve the millions of artifacts, specimens, archives and libraries in their collections for future generations. The policy focuses on both preventative and remedial conservation. Preventative conservation aims to minimize deterioration through controlling environmental factors like temperature, light, and pests. Remedial conservation treats objects to stabilize them or enhance scientific and cultural value. The policy outlines guiding principles for professional standards and safety, and details strategies for preventative conservation, remedial conservation, and disaster planning to protect the collections.
Curators are responsible for managing museum collections. They select items for display, direct acquisitions and loans, conduct research, and oversee conservation efforts. Effective curation requires documenting each item, providing access for researchers while protecting collections, implementing preventative conservation measures, controlling pests, planning for emergencies, and establishing policies for deaccessioning items. Curators ensure collections are well-managed, preserved, and made available to educate the public.
Preservation aims to extend the life of collections and includes activities like preventive care and reversible treatments. It encompasses efforts to preserve physical materials and born-digital content. The objectives of preservation are to identify materials needing treatment, evaluate and prioritize them, and apply effective and nondestructive repairs and stabilization methods. Preservation helps protect cultural heritage by maintaining access to information for future generations.

Preservation and conservation in your local museumKieran1982
This document provides an overview of preservation and conservation for volunteers. It defines preservation as managing the environment an artifact is held in and conservation as directly treating the artifact. Preservation is important to halt deterioration and allow access while minimizing damage. Factors like temperature, humidity, light, and biological agents cause deterioration. Proper storage and handling (extrinsic) can control the effects of inherent material properties (intrinsic factors). The document recommends preventative techniques like good housekeeping, housing materials, and repairs to implement preservation. Education is also presented as a low-cost way to involve volunteers and raise awareness.
A New Strategic Approach To The Museum And Its Relationship To SocietyCarrie Romero
This document summarizes a new strategic approach for museums to engage more visitors and become sustainable. It discusses how traditional blockbuster exhibitions and new buildings increased visitors initially but failed to sustain engagement. The approach focuses on supporting user interaction over broadcasting facts, and measuring success by repeated use not just visits. This was implemented at newMetropolis science center which emphasized skills development over content. The approach is now being tested at mak.frankfurt museum to transform it into a "learning platform" through new facilities, programs, collections, and accessibility measures to attract a broader audience as a "new piazza." The goal is to experiment with a new relationship between museums and society.
This document summarizes a presentation about how preservation and conservation efforts intersect with open science initiatives.

This document discusses conservation as an interdisciplinary field that involves preserving cultural and natural heritage. It defines conservation as measures to safeguard tangible and intangible heritage for present and future generations. The three main types of conservation are preventive conservation to avoid deterioration, remedial conservation to arrest current damage, and restoration to facilitate appreciation and use. Conservation requires backgrounds in fine arts, sciences, and related fields. Career opportunities in conservation include specializations in books/paper, textiles, architecture, conservation science, and more. Statutory bodies and laws in Malaysia also support conservation efforts of natural, cultural, and built heritage.
"REVERSIBILITY AND MINIMAL INTERVENTION IN THE GAP FILLING PROCESS OF ARCHAEO...Trinidad Pasies
The document discusses methods for filling in missing areas of archaeological glass artifacts. It proposes using detachable films made of synthetic materials like polyethylene terephthalate (PET) and polypropylene. These materials are commonly used in document conservation and have properties that make them suitable for reversibly filling gaps in glass artifacts. The researchers tested applying PET and polypropylene films shaped to the gaps and adhering them to artifacts, providing a reversible solution that facilitates viewing the object's form while respecting principles of minimal intervention and reversibility. Traditional filling methods often use irreversible materials like resins that damage artifacts. The researchers believe detachable films are a better alternative that balances preservation, understanding of the artifact, and respect for the original
This document discusses safety issues in museum management using HaCEM (Hazards + Causes + Effects + Measures) analysis. It begins by introducing the importance of museums to society and some challenges they face, including safety hazards. The paper then discusses previous research on safety in tourist destinations like museums. It notes that ensuring safety is important to protect visitors and staff, as well as the museum's goals. The document goes on to apply HaCEM analysis to study the possible hazards in museums, their causes, effects, and potential control measures to improve safety. This type of in-depth safety analysis could help enhance standards and sustain the growth of museums, particularly in Nigeria.
Public Awareness on Architectural Conservation in MalaysiaJing Fan Koh
The main issues affecting public awareness of architectural conservation in Malaysia are environmental, organizational, and human-related factors. Environmentally, weather conditions and the tropical climate can accelerate deterioration of historical buildings. Organizations face issues like a lack of maintenance authorities and expertise, opposing conservation philosophies, confusing laws and guidelines, and no standard conservation methods. On the human side, there are community issues like a lack of participation in conservation efforts. Poor communication and knowledge among the public are also challenges. Overall, the document discusses various internal and external barriers to raising awareness of and support for preserving architectural heritage in Malaysia.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Preventive Conservation
by Jeffrey Levin
In 1826, King Ludwig I of Bavaria began work on a n
building to house his extensive collection of Europea
paintings. The Alte Pinakothek was constructed on a
site that was then well outside the city of Munich, a
controversial decision at the time. One reason for the
choice of location was simple: It was believed that th
clean air would better preserve the paintings. The
decision was, in a sense, an act of preventive
conservation.
Until recently, conservation as a profession devoted
itself almost solely to the care of individual objects.
Mending or restoring an object--whether a Roman
bronze, a painting by Rembrandt, or a Chinese textil
was the primary function of the conservator. Today t
demands for conservation can no longer be met
satisfactorily by this approach. As both the number o
museums and the number of objects within museum
proliferate, concentrating exclusively on individual
objects severely limits conservation care for the bulk of a collection. Even the most generously
endowed institutions lack the financial and personnel resources to provide individual attention t
every object in need. For those institutions with fewer funds, sustaining any conservation progr
remains a secondary or tertiary consideration.
If a major portion of our heritage is to survive, it must be cared for collectively rather than
individually. For the conservator this means focusing on ways of preventing or slowing the
deterioration of objects through control of the collections environment. It means, in short,
preventive conservation.
Advantages and Obstacles

Preventive conservation can be defined as any measure that prevents damage or reduces the
potential for it. It focuses on collections rather than individual objects, nontreatment rather tha
treatment. In practical terms, the handling, storage, and management of collections (including
emergency planning) are critical elements in a preventive conservation methodology.
In the long term, it is the most efficient form of conservation, not only for museums, but
particularly for libraries and collections of ethnographic, natural history, and geologic materials.
With comprehensive preventive conservation, the need for individual treatments can, over time
be reduced to more manageable levels, putting personnel and financial resources to more effec
use.
Despite its advantages, preventive conservation even where understood is more accepted in
theory than in practice. The rate of deterioration in a group of objects can be slow and not fully
appreciated except over long periods. Because the deterioration rate is difficult to quantify, the
results of preventive conservation are not easily measured, nor are the results visually dramatic
since preventive conservation does not involve improving the appearance of objects. In
comparison, attending to the immediate conservation needs of an important or frequently
exhibited piece can seem far more significant--and urgent.
There are other institutional issues as well: The focus, in this age of limited resources, is often o
survival. While preserving collections is obviously essential, for many museums and other
collecting institutions conservation is not the primary concern.
"Museums are trained to survive," observes Marta de la Torre, Director of the GCI Training
Program. "In order to survive, you have to justify your existence. Organizing large exhibitions i
much easier to justify than conserving objects--because, in fact, conservation is not an end in a
of itself. It's something that you do so that you can use those objects for another purpose." By
seeking to control a museum's environment, preventive conservation, in the short term, can
require a substantial outlay of funds. It means putting money into things that may have no visu
impact, and therefore lack appeal to the public upon whose support the institution depends.
"The easiest thing in the world is to create a museum," says Paul Perrot, the director of the San
Barbara Museum of Art. "The next easiest thing is to add galleries to it. But when it comes to th
operation of these galleries--whether it's the guards, the curators, or the conservators--the fun
are not there because there's no glamour to it."
These issues, while serious, are not likely to completely obstruct the movement toward prevent
3. conservation, in part because few alternatives exist. Already there is a growing body of scientifi
research that is leading to practical applications. Nevertheless, for preventive conservation to b
effective for a particular collection, technical knowledge has to be matched with an administrati
commitment to integrate preventive conservation into an institution's operation.
Acquiring Technical Knowledge
The scientific research framework for preventive conservation involves four progressive stages:
identifying threats to collections, 2) substantiating the risk, 3) identifying cost-efficient means t
measure the risk, and 4) developing methods to reduce or eliminate the risk.
The basic problem for collections is object deterioration. "Objects deteriorate from either intern
forces or external influences," explains Jim Druzik of the GCI Scientific Program. "Of those two,
the external influences on an object are vastly larger than the internal instabilities. Things that
have existed for half a millennium have very little residual internal instability--so when they be
to deteriorate, it's purely an environmental effect."
The first step, then, is analysis of the museum environment. It is precisely in this area that the
GCI Scientific Program has concentrated much of its efforts. Following a 1984 study, with the
California Institute of Technology, on the relationship between outdoor and indoor concentratio
of ozone, the Institute examined a number of outdoor pollutants and their penetration into the
museum environment, research also conducted collaboratively. These investigations led to a se
of studies on indoor-generated pollutants. "More and more, indoor-generated air pollution is
becoming an issue that the conservation field wants to have resolved," says Druzik. "It seems
every time one turns around one sees a bronze or other susceptible material corroding in muse
storage in what is supposed to be a stable environment. Corrodants such as formaldehyde, and
formic and acetic acids are being liberated by wood products and attacking a wide range of dive
materials."
With outdoor- and indoor-generated pollutants, a number of threats have been identified and th
risks substantiated. The next stage--finding inexpensive means to measure the risks--has also
been completed.
"We've identified, and called to the attention of the conservation field, low -cost, highly sensitive
monitors," Druzik reports. "The next step is developing efficient, clever control techniques that
be applied in historic houses, older buildings, storage rooms, and display cases where the curat
or conservator simply does not have the advantage of a full blown air conditioning system with
particle and chemical filters built into it."
Microenvironments have been the subject of several GCI projects, including the development o
prototype display case for the Royal Mummies at the Cairo Museum and a study of the optimum
storage conditions for the Dead Sea Scrolls at the Israel Museum in Jerusalem. The knowledge
acquired in both projects has wider applicability for the preservation of organic materials.
In another area of preventive conservation research, the GCI conducted a joint study on pest
control with the University of California, Riverside. The study quantified and confirmed the
effectiveness of pure nitrogen as an "extremely promising" alternative to toxic chemical pesticid
in microenvironments.
A major environmental factor for any collection is the design of the building housing it. Many of
the world's museums and other collections are located in humid environments where North
American and European design solutions to environmental control are too costly and
architecturally inappropriate. Recognizing that much indigenous architecture is designed in a wa
to maximize human comfort with minimal mechanical systems (or none at all), the Institute has
begun a study of passive and semipassive systems in tropical countries. Its findings could help
lead to the development of cost-efficient environmental controls.
4. A Basic Approach
Preventive conservation does not always require expensive or complex care strategies. In many
institutions, much can be done by applying common sense.
For objects in storage, reducing the potential for physical damage can be achieved through suc
modest procedures as restricting access, exercising care in handling, and whenever possible
placing objects in individual boxes or containers.
When it has been determined that some material within the museum environment is producing
corrodants, the obvious course is to remove the offending material. If this is not easily done,
either sealing off the material or placing some barrier around it can reduce the potential for har
Alternatively, creating a protective barrier around the objects can help minimize long-term
damage.
Routine building maintenance can serve the cause of preventive conservation. Insuring that
windows and roofs are in good repair can prevent moisture damage and help moderate
temperature fluctuations that place stress on objects. Keeping both exhibition and storage spac
clean and free from dust (as well as from insects and rodents) is essential. Improving ventilatio
and air circulation through the use of low-tech fans and filters will also benefit a collection.
The Managerial Component
Because preventive conservation relies greatly on controlling the museum environment, it involv
decisions beyond the conservator's traditional authority. "If you're going to control your
environment you have to focus on your building and the different envelopes of protection," say
de la Torre. "It might be a question of reviewing the heating and air conditioning systems (if tho
exist), or creating new storage, or changing the exhibition cases, or controlling the visitor patte
You have all these things that are really not within the realm of the conservator. It's an
administrative decision."
Since 1987, the GCI has offered an annual course in preventive conservation to mid- and senio
level conservators. The approach is macro to micro, beginning with an assessment of the buildi
envelope and working down to the creation of microenvironments. While technical information
constitutes a major portion of the course material, the importance of conservators being skillful
advocates of preventive conservation is also emphasized.
Kathleen Dardes, a conservator by training, coordinates the course. She believes that for
preventive conservation to be incorporated into museum operations, conservators must not onl
develop collection care policies, but convince others of their necessity. "You can be as clever as
possible when it comes to dealing with technical matters, but if you can't speak about these thin
to the director in language he or she can clearly understand--which means understanding the
financial implications as well--and if you can't communicate to curators and exhibition designer
and if you're not prepared to work with museum colleagues, then nothing's going to happen. It
makes no difference how much you know."
De la Torre concurs. "We need to start selling preventive conservation as a feasible and viable
alternative to the management of collections," she says. "We need to start talking very
convincingly to curators and museum directors, saying, if you're going to be putting new deman
on the collections, you must make sure you're protecting them as well--and here are new meth
of protecting them that are less expensive and more efficient."
At the same time, institutions need to foster a general appreciation of collections care. Lawrenc
Reger, director of the National Institute of Conservation in Washington, D.C., thinks the public h
a genuine interest in the more "hidden" aspects of a museum's operation, and that institutions
do a better job of sharing the conservation process with the public. Reger believes museum
5. patrons are now more receptive to supporting a museum's operational needs. "People want
recognition," he explains. "I think they're willing to take on the redoing of a storeroom, as long
they get some kind of recognition. I think our goal has to be to promote this and help institution
bring this to the fore."
To Preserve and Pass On
Like nature conservation, preventive conservation of cultural heritage requires a change in
attitudes and habits. The first level of awareness is simply understanding what preventive
conservation means; the second is accepting it as a legitimate collections care strategy. The fina
and most important stage is when preventive conservation becomes an integral part of an
institution's consciousness and is put into practice routinely.
Within the last decade the number of U.S. organizations promoting preventive conservation
awareness has grown. Their ranks include the American Institute of Conservation, the Institute
Museum Services, the National Gallery of Art, and the National Institute of Conservation (NIC).
1990, the NIC and the GCI concluded a two-year project to develop a methodology for museum
professionals to amass and evaluate information on the condition of their collections. The proje
report, The Conservation Assessment: A Tool for Planning, Implementing, and Fundraising, is no
being used by museums and federal funding agencies in the U.S. as a basic guideline for
undertaking conservation assessments. But preventive conservation holds perhaps the greatest
potential for institutions located in less affluent regions of the world, where the funds and
personnel for individual treatments are in short supply. As Reger observes: "In countries with v
limited resources, this is, frankly, the best approach to take."
There is, however, no collecting institution that would not profit from a preventive conservation
program. "After all," says Paul Perrot, "preserving cultural objects for the future is a fundament
part of a museum's mission. Our historic charge is to make sure that these resources are not on
collected and studied, but preserved and passed on." For that reason, says Perrot, preventive
conservation "is good business, as well as effecting an ethical concern for objects that are withi
our care....We will certainly not arrest the march of time, but we can slow it down sufficiently so
that these objects can be more true to themselves in years to come."
Ozone Alert
Ozone, frequently employed by cleaning companies and rescue teams to
combat odors resulting from fire or flood, is known to be a high risk
chemical that should, under no circumstances, be applied to museums,
libraries, or other irreplaceable collections. Though thought to be a
modern and efficient cleaning agent, ozone is actually an irreversible and
highly destructive treatment that can damage and even destroy cultural
property.
For some time, scientists believed that ozone was dangerous principally
as a secondary pollutant in urban air. In 1984 the Getty Conservation
Institute and the Environmental Quality Laboratory of the California
Institute of Technology undertook a three-year study of the effects of
photochemical oxidants on artists' materials, with special attention to
ozone and nitrogen dioxide. Results, published extensively in the
literature, were conclusive that both pose major risks for collections.
Recent events, however, indicate that ozone continues to be used in
some museums. Reports are coming in from institutions in the U.S. and
in Europe that ozone is still proposed for use in air conditioning systems
and as a cleaning agent for smoke and water damaged materials. In one
recently reported case, ozone-induced destruction of objects made of
6. cellulose, silk, wool, leather, and metal led to litigation.
Ozone should not be used near materials of value, whether natural or
cultural, organic or inorganic. For further information, please feel free to
