The University Libraries provide access to a wealth of information: from e-journals, e-books and databases to printed material. The libraries are more than just a gateway. As a service organization we also help researchers find information, manage their data, assess the best places to publish their articles, advise on open access and copyrights and increase their impact

Access at home

Our digital resources are virtually all available from remote workspaces. For access to journals outside of the university campus, you can visit our catalogue and login to the proxy server. Even if you are only using the publicly accessible Google Scholar-database, logging in is recommended. Visiting Google Scholar via our proxy gives you immediate access to the articles you find, as long as the university has access to the publication.

Missing a book or magazine

Together with a committee of members from our faculty's institutes, the librarian tries to provide a collection that meets the researchers' demands as closely as possible for the available budget. However, sometimes it might happen that the article or book you are looking for, can't be found. In these cases you can fill out an Inter Library Loan form and we will order the item from another library at a reduced cost. If you are missing a journal instead of a single article, please contact the librarian and he will discuss with the library committee if it is possible to add the journal to the collection.

Advise on Open Access

In science there is a huge movement towards open access publishing of articles and data. Next to the ideal that anyone – from researchers in third world countries to small start-ups - can profit from research findings, open access (OA) is also easier to find and cite, can be integrated into education without additional costs and helps increase your impact as a researcher.

OA is still in its early days. Policies of funders and publishers change continuously. The University Libraries help researchers find their way in this new world. What is the difference between green and gold OA? What are my options for publishing OA in my specific fields? How can I access special grants for OA publishing? These are just some of the questions our OA librarian can solve for you.

Open Access Portal


Having a datamanagement plan is not just a good idea from the viewpoint of funders who want to increase scientific integrity and reproducibility. As a researcher you profit from having easier access to your data when you write your thesis; it also enables you to share and cite the data. Research groups profit because it becomes easier to work as a team with the same data; well-structured data can also be revived once a new Ph.D.-student builds upon an old project. The University Libraries help with setting up datamanagement plans according to the latest standards and regulations.
Datamanagement portal


The University Libraries operate several repositories to improve (open) access to the publications of its students and researchers. In these repositories you can find dissertations, bachelor and master theses as well as journal and newspaper articles from our scholars. These repositories help increase the impact of publications and can be used for scientific output analysis and visitations.

The University Libraries support students and staff with a wide range of courses on finding and using information. Amongst the subjects are gathering scientific information, preventing plagiarism, working with research data, how to publish open access, paper clinics and social media and science. Most courses are tailor-made to fit the audience. For new members of staff, we also provide individual courses. Ask your subject librarian for more information.

Copyright support

Researchers and teachers have to deal with copyright on a daily basis. The copyright information office helps out with questions such as: What does copyright entail when publishing an article and how can I prevent signing away too many rights to the publisher? What material can be used in the courses I create for my students? What should I do if someone has breached my copyrights?
Copyright Information Office

With the Browzine app you can read almost all of our e-journals such as Nature and Science on your iPad, iPhone or Android tablet as if they were printed magazines. In order to use the program, you can simply download the app from the App Store or Google Store and login with our ULCN-account.

Once you have read an interesting article, you can add it to your reference manager (Mendeley, Zotero, Endnote) or share it as a pdf with your social network. The app also allows the creation of personal libraries and alerts you once a new issue has been published.

Website of the developer

The Gorlaeus library has an extensive collection of e-books on physics and mathematics. These books are accessible through our catalogue or can be found on the special portal websites of the publishers.

Subject Librarian

For questions about the collection of the library or services of the university libraries, please contact our subject librarian Rutger de Jong. He is based at the Gorlaeus Library.

The subject librarian teaches classes in amongst others on information gathering, information reliability, dealing with plagiarism and using reference managers. Individual students and members of staff may also request personal instructions on library use and paper clinics.

Library committee

The official library committee advices on all library related matters. It consists of the subject librarian and the following representatives of the faculty’s institutes:

Prof. dr. C.W.J. Beenakker (physics)
Prof. dr. J.J. Boersema (environmental sciences)
Dr. E.H.J. Danen (pharmacology)
Dr. H.J. Hoogeboom (mathematics and computer science)
Dr. A. Kros (chemistry)
Dr. J. Lub, voorzitter (astronomy)
Dr. H.J.M. Linthorst (biology)


The libraries for the sciences can be found at two locations. Books on computer sciences and mathematics can be found at the Snellius building, other subjects are available in our library at the Gorlaeus Laboratories.
