The library for mathematics and computer science is on the second floor of the Snellius-building. At present, there is also a lecture room (B4) on the ground floor which holds printed journals. Because the Snellius library itself is unstaffed, lending is via the Gorlaeus library or by filling in a loan form.

The Special Collections department of the UBL holds a large collection in the field of mathematics, consisting of professor portraits, archives of professors, and mathematical books, such as the collection David Bierens de Haan. Search the Special Collections in the Catalogue.

Technical papers and theses are often written using the typesetting program LaTeX. However, not all reference managers are equipped to handle LaTeX. The free reference manager Mendeley, available for Windows, Mac and Ubuntu Linux, manages a BibTeX file that you can attach to your LaTeX documents. This way references can still be captured, stored and organised in one place.
