Next to the book title on some commercial sites including Amazon, you will find the LibX button for Tufts:
Clicking this button will search the Tufts Library Catalog for the book you are viewing.
* NOTE: This search uses the book's ISBN number. Different editions of a book (hardback, paperback, etc.) may have different ISBN numbers. If you receive a "no matches found" message, it may be more efficient to search for the book by title in the Tufts Library Catalog.
