*Ranganathan : He included evan audiovisual materials such as radio, television communication. But they are not documents, because they are not records on material fit for handling or preservation. Statues, material exhibits in a museum were mentioned because they convey thought expressed in some way. But none of these is a document, since it is not a record on a more or less flat surface. (ref: book: documentation and its facets, 1963).

How to search research papers?Online resource useful for teachingCitation analysis, h-index, impact factor of journals, etcPlagiarismCopyright issues
Search Electronic resources effectively
Identify and define the problemThe 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 facilitySearch facilities basic, advanced, expertCheck filters controlled vocabulary, subject headings, thesaurus, indexes, etc.Save and export references facilitiesAlert services email, RSS feedsReference Services
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 synonymsEvaluate 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.

Check search facilities
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 termsRelated 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!Source: www.library.health.ufl.edu/help/PubMed/mesh/MeshingAround.ppt
