Finding Books

Use OneSearch to find both print and electronic books in both John Jay's Lloyd Sealy library and all other CUNY libraries.  The search box can be found on our library's homepage:



To search for books only, you may want to limit your search to Books only (see above) although it is not necessary.

Search for a particular book by using an exact title and/or author or a combination of distinctive words from each to determine if the library owns the exact book you want. 

To search for books on a specific subject, type in keyword(s) and/or phrase(s) which best describe your topic.  Broaden or narrow your search if you're dissatisfied with your results.

Click on the title of those books you find relevant.

For print books:  write down the CALL NUMBER and LOCATION of the books you wish to find in the library.  Books are organized according to their location and call number:

Reference  (2nd floor, top level)

Reference Law (2nd floor, south side of building near bound periodicals)

Stacks  (books that circulate, see below)

Call number beginning with A-H are on the 2nd floor

Call number beginning with J-Z are on the 1st floor

Reserve (1st floor, Reserve desk)

For electronic booksPlease remember, not every book is digitized! But we do have many ebooks and ebook collections that are available remotely (from your home or work computer, phone, etc.).  If a book is available electronically, you will see a Full text available link in OneSearch.  Use your John Jay email ID and password to login once you are taken to the book's database site. To set up your John Jay email account or if you are experiencing difficulties with your John Jay email login, go to to set up or change your password.  If you are still experiencing problems, contact the DoIt Helpdesk at 212.237.8200 for further assistance.  

(Please keep in mind, as a general rule, electronic books owned by specific CUNY libraries other than John Jay are most probably only available to John Jay students onsite--within that owning library.  Ebooks marked CUNY are available online to all CUNY students.)

Please see our Ebooks library guide for more information for finding and using electronic books.

How to read a call number

Books on a Library Shelf

Every book has a unique Library of Congress call number. Think of the call number as the address of the book, in that it tells us exactly where, on the shelves, we can expect to find a particular book. Books are arranged alphanumerically on the shelves--first alphabetically, then numerically--by call number. 

For instance:

HA          Alphabetical by letter(s)
1625      All HA books shelved in numerical order
.O87       Further ordered alphanumerically by letter then decimal
1999      Year of publication


Four books, HA 100..., HA 1625..., HQ 16..., HV 2000...


The four books above are in the correct order.
