Naturalis library

Naturalis has a large library. We have huge numbers of books and journals on the natural world and biodiversity, ranging from leading international journals in our disciplines to popular science books.

The library is at two locations: the Naturalis Library and the Botanical Library. Together, these locations hold one of the largest collections of scientific, taxonomical and paleontological literature in the world. We cater for everyone interested in researching biodiversity, geodiversity and evolution. We also manage the library collection of the Netherlands Entomological Society. The library is almost 200 years old and contains around 200,000 books, journals, drawings, prints and many other archived materials. Once Naturalis completes its rebuilding operations mid 2019, the two library collections will be combined into a single new collection.

You can find all the publications we hold by searching N=Library.

Our shelves contain everything ever thought of by biologists and geologists


Naturalis library

The Naturalis Library specialises in publications on zoology, geology and palaeontology. As the museum is currently being renovated, the Darwinweg 2 library location will be closed to the general public until mid 2019. This library collection is temporarily being stored in a depot, where, unfortunately, we cannot receive visitors. However, we continue to offer our services relating to this collection. See Extra Saturday opening hours below.

Botanical library

The Botanical Library, which used to be part of the National Herbarium Netherlands in Leiden, contains a huge collection of botanical literature and drawings.

All items published by Naturalis or our own researchers are publicly available via the repository.

Special collections

A special room in the collection tower – the Rare Book Room – has been set aside for valuable and vulnerable paper materials. In addition to rare books, this room also houses the scientific and correspondence archives and a large collection of prints. The tower is climate-controlled so as to provide the best possible storage conditions for these paper treasures.

Many books can be consulted via the digital international platform Biodiversity Heritage Library, where you can find all the special works held by natural history libraries around the world.

Bibliotheca Carcinologica

The Bibliotheca Carcinologica is a unique collection of books in the Naturalis Library. This collection was amassed by a former curator, Lipke Bijdeley Holthuis (1921-2008), who for more than half a century was the leading expert in his field of crustacean taxonomy, including lobsters, crabs and prawns. He was particularly interested in collecting books that had been handed down by generations of his famous predecessors. Bibliotheca Carcinologica is a unique treasure trove that will provide study material for countless biologists, book scientists and scientific historians for years to come. 

Dutch natural science journals

The Netherlands has a wealth of periodicals and journals providing reliable information on Dutch biodiversity and geodiversity. Many papers from over 65 journals and periodicals are digitally available via natuurtijdschriften.nl, a platform jointly set up by the Naturalis Biodiversity Centre and various clubs and societies.
