At Northeastern's Snell Library
Search Scholar OneSearch for books owned by the Library. You may search by author, title or keyword. For example, a keyword search of "fractals and physics" (limiting to "Library catalogs" only) retrieves 75 books (8-16-18). Your search will retrieve both print and e-books owned by the library.
The library owns a number of electronic reference materials.
If the book you want is either unavailable or not owned by NU, you may request that the library borrow a copy for you to use through the library's Interlibrary Loan system.
To find what books are held by other libraries, search WorldCat, a database that searches most major, academic libraries. You can search by author, title or subject and find what books are in local libraries.
To request that the library purchase a book, you may fill out a purchase request form.
