You can find books that are relevant to your research topic in the library catalog, Tripod. Begin by developing search terms that speak to your particular interests.
If you are interested, for instance, in the movement of Jews to Latin America, you can begin with the following search: Jews immigration "Latin America". You can then build and expand on that search by using synonyms of the key terms.
Once you've identified a relevant book, you can find more like it by looking at the Virtual Browse list at the bottom of the catalog entry.
You can also find more related books by searching on the subject headings that have been applied to the book you have identified.
If you are interested in a book not owned by the Tri-College Libraries, you should first turn to E-ZBorrow, which gives you access to book collections at a number of local colleges and universities. It usually takes about three days for E-Z Borrow books to arrive.
Books not available through E-Z borrow can be obtained through Interlibrary Loan (ILL), and will arrive, once you submit the form, in as little as four to five days.
To get bibliographic information on books not owned by the Tri-College Libraries, you can turn to WorldCat. This is a combined library catalog containing more than 179 million records describing items owned by libraries around the world. Many of these titles are available to you though interlibrary loan.
