For UC Berkeley patrons

Interlibrary Borrowing Service (IBS) is available free-of-charge to UC Berkeley faculty, staff, students, and retired faculty and staff needing materials not available (e.g. the material is in-use, in process, missing, at the bindery, not owned) at UC Berkeley.

Service is not transferable, and proxy borrowers must have their proxy borrower’s card(s). If you have questions about your eligibility, contact IBS.

Other patrons with valid UC Berkeley library cards need to contact their public library's interlibrary services department.

Request a loan from a non-UC Berkeley library

  • Melvyl - Use the “Request” button in Melvyl to request items from other institutions and libraries, including other UC campuses, and international libraries. Note that eBook requests may be fulfilled instead with print copies of the title.
  • IBS Request Form - Use this form if you cannot locate the material you are looking for in Melvyl.
    • Log in with your CalNet Login information or UC Berkeley Library card/Cal1Card number and OskiCat PIN.
    • Choose the radio button that matches the type of material you are requesting, and provide as much information as possible in the available fields. Use the “Notes” field to provide any additional information (do not input personal information).
  • In-person - You can visit Interlibrary Services at 133 Doe Library where the staff can assist you with your request.
  • Pick-up and return - All IBS material is picked up at, and should be returned to, Interlibrary Services (133 Doe Library). Please refrain from returning IBS material to other libraries on the UC Berkeley campus. You can download, complete and print the book return receipt(s) and bring them to the IBS office for staff to sign and for you to keep as proof that your IBS material was returned and received by IBS. An after-hours book-drop is also available outside of 133 Doe Library for returning IBS material, though only available during Doe Library’s open hours.

Request article or part of book from a non-UC Berkeley library

  • Melvyl - Search for the publication record (e.g. journal title, conference proceedings), click on the “Request” button and follow the instructions to provide as much information on the article or part of book you need.
    • Use the “Optional note” field to add any additional information (do not include personal information).
  • IBS Request Form - Use this form if you cannot locate the material you need in Melvyl.
    • Log in with your CalNet Login information or UC Berkeley Library card/Cal1Card number and OskICat PIN.

View your ILL requests

  • Use My ILL  to view the status of your ILL requests.
    • Sign in with your Library card/Cal1Card number and OskiCat PIN (which are not the same as your CalNet Login information).
    • Once logged in, check the “Show Everything” box to view your inventory of IBS requests.
    • Renewals are not guaranteed. Click the “Renew” button to send IBS a renewal message. IBS will then contact the lender to inquire about renewal possibilities for the material. If the renewal is granted, you will receive an email from IBS notifying you of the new due date. Renewals can take up to 5 days to be granted. If the renewal is not granted, you will receive an email from IBS informing you that the renewal request was denied.

How long does it take?

  • Depending on the availability of the material at other institutions and libraries, on average, allow two weeks from the date of your request. Some items will arrive sooner and some later, depending on arrangements with the lending library.

Interlibrary Borrowing policies

  • Loan periods - The lending library sets the loan period which may range from one week to two months. IBS materials are subject to recall by the lending library at any time. Please return recalled materials immediately to insure that your UC Berkeley library privileges are not suspended. IBS requests may not be placed for material to be used for course reserve, exhibits or other long-term projects.
  • Textbooks - IBS will not borrow textbooks for current UC Berkeley courses.
  • Special conditions - The lending library may impose special conditions on the use of their material. Common conditions include: library-use only, for use in The Bancroft Library, non-renewable, no photocopying, or user's signature required. Conditions are noted on the IBS book band attached to the material. When you accept the IBS loan, you are obliged to honor these conditions.
  • Special materials - Many Libraries will not lend rare, fragile, new or unique materials. Also they may not lend whole volumes of recent periodicals, recent textbooks, DVDs, e-books, or special collection materials.
  • Loss and damage - As the borrower, you are responsible for any damage to or loss of IBS materials from the time you pick them up until you return them to the IBS office. You are also responsible for damage caused by scanning or copying from the material, even if no specific restrictions are noted on the IBS book band. Should any damage occur, report it to IBS. Do not attempt to repair it yourself.
  • IBS will not process requests for materials which UC Berkeley owns and is listed as AVAILABLE in the OskiCat catalog.
