Access to digital material licenced by Utrecht University Library

You have access to digital material directly from the search results in WorldCat. Click on the blue button with "view full text", "view eBook", "Access journal", "Listen to audio", "View now" or "Access online".

When you are searching for e-journals, we recommend you to use the list of e-journals (in WorldCat). Using the general search options in WorldCat is less suitable for this purpose.

If an article is published in open access, it is always available. Besides, the library has many licenced resources you can access. If you are on campus you have access straight away, if you are off-campus you will have to log in with your Solis-id or UMCU-account first. For more information please read the page about online access.

Access to printed material

You will find printed material from the Utrecht University Library collections in WorldCat. The availability of these items and where to find them is directly shown on the page with search results. Click on the title if you cannot immediately see where the book is located.

Requesting and borrowing

You request items by clicking on the "Request item@UU" button. If items are on loan to other borrowers you can use the "Request item@UU" button to reserve them. You will be asked to log in with your (guest) Solis ID.
