Can't find it at UBL

In case a publication is not available at Leiden University Libraries (UBL), there are several options to obtain it from another library.

Availability in other Dutch libraries can be checked in PiCarta. Leiden University students and staff may obtain a library card free of charge at any of the Dutch university libraries; the Royal Library (KB) offers a 50% student discount.

For a fee, the UBL also offers inter-library loan services (ILL).

PiCarta search

Leiden University students and staff may consult PiCarta using their University account. An ILL account is needed only when placing requests.

Alumni and guests may consult PiCarta without an ILL account, from within the Leiden University network. In order to consult PiCarta elsewhere please have an ILL account made.

The PiCarta help function offers extensive information on search strategies.

Creating an ILL account

Library patrons can have an ILL account made at the desk of the University Library, the Social Sciences Library, or the Law Library. Requests are paid for in advance from the deposit made into your account.

The library where your account was made will be your ILL home library; this is where you collect and return books, report a change of address, inquire after your password, and make deposits into your ILL account.

Requesting materials

Your PiCarta logon data are the 'personal number' on your LU-Card - including the lower case 's', 'm', or 'g' - plus your ILL account password. 

Both the University Library (UB) and the Wijnhaven Library in the Hague offer the option to use ILL services without a PiCarta-account. At the library desk you will find request forms to fill out. 

Delivery times can range from a week to ten days. Books can be picked up and returned at the library location where you opened your ILL account. The UBL circulation policy applies.

Making deposits into your account

Deposits made into your ILL account at the library desk will be directly at your disposal.

Patrons holding an ILL account at the University Library (UB) may also transfer the desired sum to bank account number NL98RABO0103258477 of Universiteit Leiden, cs Bibliotheek, Leiden. Please mention 'ILL account' plus the personal number on your LU-Card, including the letter 's', 'g', or 'm'. Processing bank transfer payments may take several days.

Viewing or changing your account information

In PiCarta under 'my account' you may check active and past requests, your deposit, and personal data registered to your account. You can change your email address directly in PiCarta; a change in your postal address needs to be registered at the desk of your UBL location.

International loans

If a publication is not held by any of the Dutch libraries participating in PiCarta, you may request the library to try and obtain it through international ILL. Please contact the library desk of your UBL location. Requests for publications that can be purchased online for a reasonable price will not be processed.

International ILL loans may be checked out, unless the lending library stipulates otherwise. Delivery times for international ILL may vary.
