Distributed Catalogue Code and Standards.pdfPravatKhadka
Distributed Cataloguing:
Computerized cataloguing provides a unique advantage of loading and merging of bibliographic and authority records from external databases. This feature of an automated system leads to a reduction in cataloguing effort and a consequent saving in the unit cost of cataloguing. This mode of shared cataloguing is popularly termed as copy cataloguing and implemented in libraries thorough:
Merging of existing machine readable form of cataloguing data with the catalogue database
Relevant and appropriate recordsfrom external databases (union catalogues or commercially available catalogue datasets) in magnetic or optical media may be added to the catalogue database, after modification to match local requirements (e.g. indication of added entries, references) and the addition of local data (e.g. call number, accession number, location).
Downloading of bibliographical data of relevant records from any Z39.50 server (version 2 or version3) including but not limited to OCLC, RLG, and Library of Congress etc. This facility is achieved through the incorporation of Z39.50 copy cataloguing client in the catalogue module of the package.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

3. Meaning
Z39.50 is an international standard protocol used by networked computer systems for
information retrieval. It enables information seekers to search different systems on a network
or the Internet through the use of a single user interface.

4. Definition
ANSI/NISO Z39.50 – is a protocol which specifies data
structures and interchange rules that allow a client machine (as
called an “origin” in the standard) to search databases on a
server machine (called a “target” in the standard) and retrieve
records that are identified as a result of such a search.
7. Functions
Main function is to provide information's to user’s by information retrieval.
The basic function of Z39.50 is to negotiate a connection between the client and
server on two systems, execute a search, and return the formatted results to the
user’s screen. In a Z39.50 session, the Z39.50 client software that initiates a
request for the user is known as the Origin.
The Z39.50 server software system that responds to the Origin’s request is called
the Target.
9. Versions
1. Version 1 was released on 1988 which was a standard way to provide bibliographic details i.e.
core services
2. Version 2 formalized the structure of information to be exchanged based on the ISO standard
data description language and encoding rules. Released on 1992
3. Version 3 the current version of the standard, builds on and includes version 2. Version 3 is
extremely powerful in its support for simple to highly complex applications. The current
version of the Z39.50 standard is formally known as ANSI/ NISO Z39.50-1995, Information
Retrieval—Application service definition and protocol specification.
4. Version 4 was released on 2003.

12. Z93.50 Profile
A profile is a detailed specification of Z39.50 features and functions that an implementation will
support, improving interoperability by;
Assisting customers in specifying requirements for Z39.50 products,
Defining a core set of Z39.50 features to assist vendors in configuring their products,
Increasing the market for Z39.50 products,
Improving users’ success in information retrieval, and
Leveraging local investment in Z39.50 by providing global access to resources.
13. Advantages & Examples
It increases the reliability of results as a profile will define the attributes and attribute
combinations, which are supported by server.
Profile will help in standardising the server configuration.

15. Z-39.50 Globally
Z39.50 is recognized worldwide as the international standard for networked information
search and retrieval. Internationally, many library software vendors, bibliographic
utilities, commercial sector, and government organizations have adopted Z39.50
functionality in their products. The broad range of accessible information includes;
Bibliographic data
Government information
Scientific and technical data
Geospatial data
Thesauri and other taxonomies
Digital library collections
Arts and humanities data
Museum information
16. Advantages
Any database that is Z39.50-enabled may be searched by using a single search interface, a
single set of search commands and search strategies.
Allows intersystem searching and record transfer irrespective of different software and
hardware.
Multi-database searching using single search interface.
Virtual union catalogue--a combined catalogue of several libraries on diverse systems (without
merging the catalogues) is possible.
Interlibrary loans (ILL) process will be made easier.
Records can be displayed in any flavour of MARC
CD-ROM databases from various vendors could be searched with a single interface.
The SDI or selective dissemination of information service could be set to run a saved search in
the catalogues of many different libraries regularly and automatically with results being sent to
the user by fax or e-mail.
17. Disadvantages
Very complex.
Levels of services supported within and between the particular
implementation depend on Z-client/Z-server and host library management
system.
The differences between the facilities on Z-client and Z-server lead to poor
output.
Multi-database searching leads to slow response time and information
overload.
18. Z39.50: current & Future
ZING is the umbrella name that has been given to the whole set of experiments going on that
are attempting to look at what possible next generation versions of Z39.50.
“ZING, "Z39.50-International: Next Generation", refers to a number of initiatives by Z39.50
implementors looking at evolving Z39.50 to a more mainstream protocol attractive to
information providers, developers, vendors, and users.
Currently, there are experiments going on under the general ZING umbrella
One ZING experiment, begun in the summer of 2001, is called the Search/Retrieve Web
Service (SRW). This approach uses standard web technologies including Extensible Mark-up
Language (XML), Hypertext Transfer Protocol (HTTP), Simple Object Application Protocol
(SOAP), and Web Service Description Language (WSDL) to create a lightweight information
retrieval protocol that fits in the context of web services.
SRW retains several key Z39.50 concepts such as abstract access points using Z39.50 attribute
sets within a simple query structure called an experimental Common Query Language (CQL).
ZOOM, the Z39.50 Object Oriented Model, is a separate ZING initiative. ZOOM is developing
specifications for application programming interfaces (API) to build any kind of Z39.50 client
or client-based service. It uses Perl, c++, java.
19.
20. Conclusion
Z39.50 is protocol that is used for information retrieval from
various libraries, information centres, data centres, museums, and
to locate exact information from and to retrieve for the particular
users needs. The Z39.50 protocol not only rescues a librarian
from learning different search interfaces for different databases,
it also helps the librarian to improve resource sharing among
libraries by virtual union catalogue and ILL.
