Registration requests for the library system, for access to the loan service and reading rooms during periods of extraordinary opening, from people who are not part of the university community but have a contractual relationship with the university (e.g. service companies, cleaning companies, access controllers), will be channelled through an external endorsed user.

This type of endorsement can be made in two ways:

1. If the person needs the discharge because of his/her work in the library service, the endorsement can be made by the director or coordinator of the library he/she joins.
2. In any other circumstance, the endorsement must be requested from the head of the service to which he/she belongs or the campus unit.

Once the endorsement has been made, incorporation into the library system is automatic, as it is for the rest of the university community's staff.

In none of these cases will a physical card be issued. If a user needs a physical library service user card, they must expressly request it using the same form as research staff without a university card (endorsed) that appears on the website.
