Library guest accounts and LU-Cards

Due to technical adjustments, from 19 December until 5 January no new library accounts and or LU-Cards can be made at Leiden University Libraries. Existing accounts cannot be renewed during this period. We expect these services to be fully functional again starting 5 January.

ULCN account passwords

From 19 until 30 December, ULCN account holders (Leiden University students, staff, alumni, and guest users) cannot change their password for immediate use. Any password changes made during this period will be expected to be operational after 30 December.
