Since the library's conversion to bMail, notices from Interlibrary Services are frequently being routed to the recipients' SPAM or JUNK folder.

Please check these folders, mark the messages NOT SPAM or move them to your INBOX. Once you do this, subsequent messages should automatically be directed to your INBOX.

If you forward your bMail to another e-mail service, your SPAM folder will NOT forward. You will need to log into bMail directly to check the SPAM folder.

The Interlibrary Borrowing Service (IBS) supports the instructional and research needs of UC Berkeley's students, faculty and staff by obtaining materials which are not available at UC Berkeley libraries. IBS is one of the largest and most sophisticated library resource-sharing operations in the country. IBS belongs to major library networks and utilizes several computerized systems to acquire materials from libraries throughout the United States and the world.

See Your ILL Requests:


The service is available free of charge to UC Berkeley faculty, students, and staff. Other patrons with current UC Berkeley library cards are encouraged to use their public library's interlibrary loan service. Service is not transferable, and proxy borrowers must have proxy borrowers cards. If you have questions about eligibility, inquire at the Main Library Privileges Desk or at the Interlibrary Services Office, 133 Doe Library.

How To Use the Interlibrary Borrowing Service

Check OskiCat (UC Berkeley's library catalog) to make sure UC Berkeley does not own the material you want. IBS cannot process requests for materials which UC Berkeley owns.  If you need help using our catalogs, inquire at the Reference Center on the second floor of the Main Library or at the Reference Desk at any subject specialty library.

Provide a full and accurate bibliographic citation, including author, title, place and date of publication, and series.

To verify a book citation use:

MELVYL Catalog
    Search all UC libraries
    Search libraries worldwide (includes UC)
National Union Catalog

To verify a serial (e.g., journal, magazine, or newspaper) citation use:

MELVYL Catalog
    Search all UC libraries
    Search libraries worldwide (includes UC)
Union List of Serials
New Serials Titles

To verify a dissertation citation use:

ProQuest Dissertations & Theses
MELVYL Catalog
    Search all UC libraries
    Search libraries worldwide (includes UC)

Reference staff can help you with these, or suggest other sources as appropriate. If you cannot find the item you need in the suggested sources, provide us with a photocopy of your reference (typically the title page and the page including the citation).

Submitting Requests

Berkeley Faculty, Students, and Staff may request items found through the Melvyl catalog by using the request feature on that system. Journal, magazine, and newspaper article requests may be made through UC-eLinks in the various article databases.

Berkeley Faculty, Students and Staff may submit requests electronically by clicking on the request form button below to order an item.

Requests may be made in person at the Interlibrary Borrowing Office (133 Doe) where staff can advise you about your request. Requests may also be submitted at the reference desk of most Subject Specialty Libraries.

Pick up and return items through IBS at the IBS office, room 133 Doe Library. An after-hours book return is available outside Room 133.

BAKER users can submit requests to IBS through the Baker service.  BAKER is a fee-based document delivery and bibliographic verification service. BAKER delivers materials to your campus address. For further information about this service, email or call 642-2538.

How Long Does It Take?

On the average, allow two weeks from the date of request.

Special Conditions

The lending library may impose special conditions on use, such as library use only, for use in the Bancroft Library, non-renewable, no photocopying, or user's signature required. Conditions are noted on the IBS band attached to the book. When you accept the loan, you are obliged to honor these conditions.

Loan Periods

The lending library sets the loan period, which may vary.

Materials Generally Not Available Through Interlibrary Loan

Some libraries have categories of materials which are not available on Interlibrary Loan. Examples are: rare, fragile, or unique materials; audiovisual material; some dissertations; whole volumes of recent periodicals; and items in special collections.

In some cases facsimile copies exist (usually microfilm) and these may be sent on Interlibrary Loan. The UC Berkeley Library has arrangements with a number of libraries which provide access to some of these restricted materials. You will be advised of such general limitations when you submit your request.


You, the borrower, are financially responsible for any damage to or loss of interlibrary materials, from the time you pick them up until you return them to the IBS Office. You are also responsible for damage caused by photocopying, even if no specific photocopy restrictions are noted on the material. Should any damage occur, report it to IBS. Do not attempt to repair it yourself.
