As of now, UZH staff members can have a research collection (RC) created. In this way, documents from their the own UB location can be kept longer than it's possible with a normal loan.
A research collection can contain between 10 and 100 items and the items can be borrowed for 2 semesters. If the project is not completed after that, the term can be extended.
A research collection can be requested using an application form. Here you find the form and all other information.
