With full-text searching capabilities, Google Books can be an excellent supplement to using the online catalog. Try doing a keyword search for your topic to identify titles that might be useful for your research. You may be able to preview the items on Google Books, but don't forget to do a title search for the item in WSU WorldCat in order to view the full physical copy (or electronic version, when available). You may also be able to preview books directly through WSU Worldcat by clicking the "Preview this item" button from the catalog record.
SearchIT is a catalog that lists not only WSU material, but also books that may be available through Summit, and Inter Library Loan.
In addition to books, you can search SearchIT for journal articles, Internet resources, and media.
When searching SearchIt, you will be able to tell if a book is available at your campus when a green light is visible next to the "Avilable at" location, such in the example below! If a yellow light is in its place, the item may still be requested through Summit or Inter Library Loan.
