Evaluation Tips for Online Resources

If you choose to use resources from the open web (e.g. websites you find in a Google search), keep the CRAAP test from the CSU, Chico Meriam Library in mind:


  • When? Publication date, post date, updates


  • Related to your topic, Intended audience


  • Who created it? Are they qualified to write on the topic?


  • Where does the information come from? Evidence? Reviewed? Unbiased?


  • What is the purpose of the resource? Inform, teach, sell, entertain or persuade? Is it fact, opinion or propaganda?

Evaluating information is an essential step in quality research.

Search for Books, eBooks and Print Journals

The library's online catalog, Alexandria, can be used to find both books and ebooks.

Books in the standard collection may be borrowed for three weeks. Books placed on reserve by your professor will have a shorter loan period. Books not available from the library can be borrowed through AcademicSHARE or Interlibrary Loan (ILL). Contact the library for help. To find items held by Villa and other libraries, try WorldCat.
