See our Ebooks guide for detailed information on using our Ebook collections.
The library maintains a catalog of the print and electronic items in our collections. Search it to find out which books, journals and other items the library owns.
Materials in the Library are arranged by call numbers on the shelves. The library has "open stacks," which means library users locate the materials they need themselves; no permission is needed.
Some of the most commonly used materials are in these collections:
NPS students may borrow most materials for a period of 3 months. There are exceptions. Find out more about borrowing privileges.
To find NPS theses use Calhoun, the NPS Institutional Archive.
If you need materials our library does not own, we can borrow them for you from other libraries. Find out more about Interlibrary Loan.
The catalog can be used to locate books, journals and other items the library owns, but cannot be used to locate journal articles. Finding technical and professional literature in journals requires the use of indexes or "databases". Find our databases on our Articles & Research Databases page.
