Try specific terms first,
then try more general ones.
Searching specific terms may miss a book about the broader topic that has just a chapter on your topic.
If you have them, use both the scientific and common names for organisms, connected with or.
Try using truncation (microb* will find microbe, microbes, microbial, and microbiology) and variant spellings so you won't miss important titles.
To get a book delivered to campus from one of the other Four Colleges, click REQUEST at the top (left) of its catalog record and use your library barcode number. You will receive an e-mail in 1-3 days to pick up the book at the UMass Library.
TIP: Use WorldCat Local, the default search on the Library's website, for the widest search, when you are exploring a topic for the first time - it finds books anywhere, whether the UMass Libraries have them or not.
If the book is not available in the Five College Library System, you may request a copy through InterLibrary Loan and Document Delivery.
