Articles found in them can provide you with both primary and secondary sources of information. They usually cover topics that are narrower in scope. Carefully evaluate the periodicals you use for sources. Answering these questions will help you evaluate the information that you obtain. To find articles on your topic you must use Periodical Indexes and Abstracts.
Abstracts have a short summary of the articles in addition to the indexes already mentioned.
Consult the indexes or abstracts appropriate to your topic, and then check the Online Public Catalogue to see if what you want is in the Library. If the Library does not have the particular publication you need you can still obtain it through the Library's Interlibrary Loan Service. To use this service ask at any Library Circulation or Reference Desk. The list that follows details some of the Periodical Indexes that Engineering Students may find useful.
