In order to find books held in the University of Maine System libraries you should begin with LibrarySearch, the online catalog.
If the material you need is not available at the USM Libraries, you should next search MaineCat and Request the material. If the book is not available through LibrarySearch or MaineCat, then you should create a free Interlibrary Loan (ILLiad) account. See links below.
