Academic Libraries: Typical Information Sources
Searching the Online Catalog vs. the old Card Catalog
Most of the results in any single OPAC search will be print books, since currently the print collection still outnumbers the online collection.
However, the OPAC will also identify all other materials in the collection, including E-Books, audio / visual materials, journal titles, and microfilm / microfiche.
Books: Print vs. Online Collections
The OPAC will identify all printed books held within the library. Each book has been assigned a Library of Congress call number, which pinpoints the location of where the book is shelved. Books on similar topics will be shelved nearby, and will have similar call numbers.
To find this sample call number, GC231.2 .H65 2011, look first for the G's, then the GC's, then the GC 200's, and GC 230's, then GC 231.2, etc., etc., etc... For more on call numbers see Library of Congress Classification System.
The OPAC will also identify the library's online books. A keyword search in the OPAC will typically bring a mixture of print and online titles. Most libraries have one or more online book collections (eBooks), which may be searched individually. Unlike the OPAC, these E-Book collections will allow for a search within the entire text of these online books. An example is the Gale Virtual Reference Library.
Journals, magazines, & newspapers are published 'periodically,' hence the term 'Periodical Databases.'
A 'Keyword' search in a periodical database will search anywhere within the:
- article title
- journal title
- subject headings
- abstract (summary of the article)
- author's name (author of an article)
Most periodical databases have a mixture of full text articles and some items where there is only an abstract (summary) of the article.
Find any article on a given topic; or find a specific article.

The terms Refereed, Peer Reviewed, Academic, and Scholarly are often used interchangeably.
To be published in a peer reviewed (or refereed) journal, the article must be read and approved by other scholars in that field of study. For more on how to distinguish a scholarly journal from a popular magazine, see the Sawyer Library guide: Peer Review and Primary Literature: An Introduction.
Aren't Wikipedia and Google just as good as the periodical databases?
