Additional guidelines for digital libraries

Guidelines home
Draft version 0.1

What is different about digital libraries?

“Digital libraries demand more sophistication of query formulation than web search engines such as Google™; skills acquired in one library environment are often not easily transferred to another.” [1]

Detailed guidelines

The additional guidelines can be used in conjunction with the web usability guidelines for academic websites:

 

Digital libraries

1

Design Process and Evaluation

1a

To design good, usable digital libraries, one requires knowledge about who will use them, what they will be used for, the work context and the environment in which they will be used, and what is technically and logistically feasible. [3]

1b

Copy an interface that is already widely used and successful (e.g. a similar service) to facilitate transfer of learning [1]

1c

User should be able to focus on their task rather than how the DL works [1]

10

Links

10a

Links should be embedded in the documents to provide users with the ability to move to related information quickly without having to waste time submitting another query and waiting for the query results. [3]

15

Writing Web Content

15a

Documents (content) should be easy to read or skim [2]

15b

Do not overwhelm the user with text, keep it simple and informative [4]

15c

Use meaningful document header to identify the content of the document and page footer to identify the origin, authorship, author contact information, date of creation, copyright info, etc. [3]

15d

Match the system to the real world. Simulating an existing artifact can improve the integration of the DL with current work practices. [4]

17

Search

17a

Provide clear information about which libraries are available to the user and the scope of content of each library. [1]

17b

Support browsing to find how well does a collection covers a topic area [2]

 

Clearly indicate when entering or leaving a particular library search environment. [1]

17c

Users do not want to receive all the results, they prefer a manageable number that are easily distinguishable in terms of the documents' content [1]

17d

Users will give up unless they find relevant material rapidly, and really want new, interesting, and possibly surprising material.  [1]

17e

Allow people to save, modify, and review queries for reuse over time. [2]

17f

Offer alternative search forms for users with different understanding of the content (advanced and novice) [4]

17g

Eliminate as much typing as possible, support abbreviations and acronyms for advanced users [4]
