College Information Literacy center

Definition Information literacy is a set of abilities requiring individuals to "recognize when information is needed and have the ability to locate, evaluate, and use effectively the needed information.“

Library can play a role in increasing the Information literacy of students and teachers

Determine the extent of information needed Access the needed information effectively and efficiently Evaluate information and its sources critically Incorporate selected information into one’s knowledge

base Use information effectively to accomplish a specific

purpose Understand the economic, legal, and social issues

surrounding the use of information, and access and use information ethically and legally

For literacy one needs to learn How to use Digital and Electronic Libraries available at

college? How to search various electronic databases? How to use Search Engines? How to create information alerts? For teachers

– How to search research papers?– Online resource useful for teaching– Citation analysis, h-index, impact factor of journals, etc– Plagiarism– Copyright issues– …

Search Electronic resources effectively

Identify and define the problem The scope of the topic, i.e., the breadth and depth of

information required Appropriate criteria to direct the search process; i.e.,

– What type of information is required?– For what purpose will it be used?– How much information is required?– What form or limitations (if any) should be placed on

the information to fit? Identify appropriate databases as information sources

Before you search

Check for login facility Search facilities – basic,

advanced, expert Check filters – controlled

vocabulary, subject headings, thesaurus, indexes, etc.

Save and export references facilities

Alert services – email, RSS feeds Reference Services

Check list before you search any database

Select multiple search terms and synonyms appropriate for the database(s); i.e., what words or phrases best describe the core concepts. 

Construct search queries from the search terms and synonyms

Evaluate the items retrieved by the search query(ies); i.e., does the information retrieved as result of the query(ies) satisfy the criteria identified at the beginning of the process.

Before you search

In most cases, you will have to use more advanced methods, involving combinations of several search terms. For this you will have to define a search strategy, a plan of action that helps you find the information you need. This requires you to think about your subject, work out what information you need, and how you're going to find it.

The first step is to split your subject into main themes and identify keywords.

Building a search strategy

These ‘keywords’ can then be used to search for relevant references in databases.

After identifying main keyword/phrases you have to think of additional subject headings to ensure you find all the information about your topic.

Building a search strategy

Finding the right search terms Related terms

represent ideas associated with the subject you are looking for, but are not exact synonyms.

Most often the synonyms and related terms you will need to identify will be additional terms with roughly the same meaning.

Combining search terms - Boolean operatorshttp://library.wur.nl/desktop/guide/

Check thesaurus, indexes..

Subject headings link all synonyms/grammatical forms/spelling variations together.

So… pick the right subject heading and all the possible words/forms come along!
