This document summarizes Nicholas Belkin's theory of anomalous state of knowledge (ASK), which proposes that information needs arise from gaps or anomalies in a person's knowledge. It compares the traditional information retrieval model to Belkin's ASK model, which recognizes that users may not be able to precisely specify their information need when they have an incomplete understanding. The document also outlines some applications of anomaly detection and discusses implications of Belkin's theory, such as the need to represent information needs differently than the best-match approach used by most search systems.
This document discusses policies and procedures for developing library collections. It provides definitions of collection development policies and their purpose. A collection development policy formally guides a library's selection of materials by outlining criteria for inclusion, exclusion, and weeding. It aims to create a balanced collection that supports the library's mission and allows librarians to rationalize decisions. The document suggests questions a policy should answer and elements it should include to effectively plan, select, and manage a library's resources.
The document discusses data indexing, which is a data structure added to files to provide faster data access. Indexing reduces the number of blocks a database management system must check when performing operations like reading, modifying, updating, and deleting data. An index contains a search key and pointer, where the search key is used to look up records and the pointer contains the address of stored data. Common indexing techniques include ordered/primary indexes that access sorted data and hash indexes that uniformly distribute data across buckets. When choosing an indexing technique, factors like access type, time, space overhead are considered. B-trees are commonly used indexing data structures that can grow and shrink dynamically with root, branch and leaf nodes.
This document reviews different search and retrieval strategies used to locate information from databases. It discusses formulating search queries using keywords and concepts, selecting relevant databases and resources, and employing various search techniques like Boolean, truncation, proximity and field-specific searches. The document also outlines the search process of reviewing and refining results and concludes with the importance of search strategies for library professionals and information seekers.
This document discusses professional ethics for librarians. It begins by defining ethics as moral principles that govern conduct. It then defines a profession as work requiring specialized training where success is measured by service rather than financial gain.
The document outlines the ethics codes for librarians, which focus on duties to users, the profession, colleagues, the organization, and society. It emphasizes service orientation and avoiding conflicts of interest. The duties of librarians include caring for books and users, developing the profession, treating staff and colleagues well, and continual self-improvement. Maintaining high professional standards and putting users first are emphasized.
This document discusses library portals and their importance. It defines a library portal as a combination of software that unifies the user experience of discovering and accessing information. Library portals are important because they can help address the problem users face in navigating the many dispersed electronic resources and databases available. Portals allow a single point of access and can integrate various library services and tools. However, there are no accepted standards for library portals currently.
The document provides an overview of computers and their components, peripherals, and uses in libraries. It discusses desktop computers and their essential parts like the motherboard, processor, RAM, and ROM. It also covers computer storage media, measurements, software types, operating systems, and a brief history. Additionally, it lists common peripherals like monitors, keyboards, mice, printers, and their varieties. Finally, it discusses how computers are used for tasks in libraries like collection organization, interlibrary loans, electronic resources, internet access, instruction, and more.

The goal is to make libraries more relevant and responsive to changing user needs and technologies.
The Library in the Life of the User: Two Collection Directionslisld
Our understanding of library collections is changing in a digital, network environment. This presentation focuses on two trends in this context. First, the inside-out library is a trend which sees libraries support the creation, management and discoverability of institutional materials: research data, expertise, preprints, and so on. Second, the facilitated collection is a trend which sees libraries increasingly organize resources around user interests, whether these resources are external, collaborative or locally acquired.
This presentation was given at 'The transformation of academic library collecting: a symposium inspired by Dan C. Hazen'. Harvard Library, 20/21 Oct. 2016

The document outlines 10 usability heuristics for user interface design: 1) keep users informed of system status, 2) use language familiar to users, 3) allow users easy exit from unwanted states, 4) be consistent in design, 5) prevent errors from occurring, 6) make needed information visible rather than requiring recall, 7) support both inexperienced and experienced users, 8) avoid unnecessary information, 9) help users recognize, diagnose, and recover from errors, and 10) provide help documentation that is easy to use. It also describes a workshop where groups will evaluate examples based on 2 assigned heuristics.
This document discusses evaluation techniques for user interfaces, including cognitive walkthroughs and heuristic evaluation. It provides details on how to conduct a cognitive walkthrough, which involves experts walking through a design to identify potential usability issues. It also describes Nielsen's 10 usability heuristics for heuristic evaluation, such as visibility of system status and user control. Examples are given to illustrate how each heuristic can be applied.
Ten Usability Heuristics by Jakob Nielsen.pptxsharmiladevi941
1) The 10 usability heuristics provide guidelines for interface design including visibility of system status, matching the system design to real world concepts, giving users control and freedom, maintaining consistency, preventing errors, using recognition over recall, providing flexibility and efficiency, having an aesthetic and minimal design, helping users recover from errors, and providing helpful documentation.
2) Some key guidelines within the heuristics are to always inform users of the system status, speak the user's language with familiar concepts, clearly label ways to exit tasks, maintain consistency across interfaces, eliminate error-prone conditions, reduce memory demands on users, allow for customization and shortcuts, remove unnecessary elements, and give constructive error messages.
3) The
This document provides summaries of several guidelines and methods for human-computer interaction (HCI). It discusses Shneiderman's Eight Golden Rules for designing user interfaces, Norman's seven principles of interaction design, Norman's model of the interaction process, Nielsen's ten usability heuristics, contextual inquiry for understanding user needs, and cognitive walkthrough for evaluating design. The summaries focus on key principles for making interfaces easy to use, learn, and remember through consistency, feedback, affordances, mapping to real world concepts, error prevention, and minimizing memory load.
This document discusses heuristic evaluation as a usability testing technique. It defines heuristic evaluation as a practical approach to problem solving and discovery that may not be optimal but is sufficient for immediate goals. The document lists Nielsen's 10 usability heuristics for interface design, such as visibility of system status and user control and freedom. It provides examples for each heuristic and advises that heuristic evaluation should not replace talking to users, but can help identify usability issues before user testing.
A heuristic evaluation is a usability inspection method mainly used to identify any design issues associated with the user interface.

Evaluation techniques can be used at all stages of the design process to test interfaces and identify problems. There are two main categories of evaluation: expert analysis and user participation. Expert analysis includes cognitive walkthroughs, heuristic evaluations, and review-based evaluations. User participation evaluations involve testing with users and can be done in laboratories, fields studies, or experiments. A variety of techniques exist within each category to gather both qualitative and quantitative feedback. Choosing an evaluation method depends on factors like the design process stage, desired objectivity, and available resources.
The document outlines Jacob Neilsen's 10 general principles for user interface design, called heuristics. The heuristics are broad usability guidelines rather than specific instructions. They include visibility of system status, matching systems to the real world, user control and freedom, consistency and standards, error prevention, recognition over recall, flexibility and efficiency of use, aesthetic and minimalist design, helping users recognize, diagnose and recover from errors, and providing help and documentation.

5. Evaluation Plan
Examine
● Get trained
● Each heuristic expert will evaluate
List
● Individually list down problems found based
on 10 principles of heuristic evaluation
Collate
● Club all problems of all evaluators in a caveat
● Rank on the basis of severity
Fix ● You’re already an expert on that!
7. # 1
Visibility of
System Status
The system should always keep users
informed about what is going on,
through appropriate feedback within
reasonable time.
8.
9.
10.
11. Which is the most important status we
want to know these days?!
12.
13. ● Browser/App/Program name
● Favicon
● Logo
● Page heading
● Section heading
● Selected Tab
● Progress bar
● Loader
● Micro interactions
● Click/Hover/Any event Interaction
● Updated information
14. # 2
User control and
freedom
Users often choose system functions by
mistake and will need a clearly marked
"emergency exit" to leave the unwanted
state without having to go through an
extended dialogue. Support undo and
redo.
21. # 3
Recognition rather
than recall
Minimize the user's memory load by
making objects, actions, and options
visible. The user should not have to
remember information from one part of
the dialogue to another. Instructions for
use of the system should be visible or
easily retrievable whenever appropriate.
25. # 4
Match between
system & the real
world
The system should speak the users'
language, with words, phrases and
concepts familiar to the user, rather
than system-oriented terms. Follow
real-world conventions, making
information appear in a natural and
logical order.
37. # 6
Flexibility and Ease
of Use
“Accelerators”
— unseen by the novice user
— may often speed up the interaction
for the expert user such that the system
can cater to both inexperienced and
experienced users. Allow users to tailor
frequent actions.
42. # 7
Help users
recognize, diagnose,
and recover from
errors
Error messages should be expressed in
plain language (no codes), precisely
indicate the problem, and constructively
suggest a solution.
43.
44. Properties of error messages:
● Explicit
● Human Readable Language
● Precise
● Constructive
● Polite
45. # 8
Error prevention
Even better than good error messages is
a careful design which prevents a
problem from occurring in the first
place. Either eliminate error-prone
conditions or check for them and
present users with a confirmation
option before they commit to the
action.
48. # 9
Help and
documentation
Even though it is better if the system
can be used without documentation, it
may be necessary to provide help and
documentation. Any such information
should be easy to search, focused on the
user's task, list concrete steps to be
carried out, and not be too large.
49. Type-1: Detailed documentation
Type-2: Community centres
Type-3: Question and Answers examples normal chat, chat-bots
There are product companies based on Help & Documentation provide
integrations for example StackExchange, ZenDesk, BotsCrew, Haptik

50. # 10
Aesthetic and
minimalist design
Dialogues should not contain
information which is irrelevant or rarely
needed. Every extra unit of information
in a dialogue competes with the
relevant units of information and
diminishes their relative visibility.
53. Severity Rating
Ranges from 0-4
0 - I don’t agree that this is a Usability Problem at all
1 - Cosmetic Problem. Fix it only if we have extra time
2 - Minor usability problem
3 - Major usability problem
4 - Usability Catastrophe
54. Tips
● Go through the interface back and forth 2-3 times then start evaluating.
● Don’t perform the real task, explore!
● Open google doc, for each problem write:
a. Problem details
b. Screenshot/Video/GIF
c. Severity rating
d. Heuristic
e. Why does that heuristic apply
