Once you arrive please press the buzzer or telephone 0207 449 6293 so one of the Library Team can let you into the building.

Although some restrictions have been lifted our priority is to keep you and our staff safe so we would appreciate you complying with some safety measures.

  • Please also wash your hands on arrival. We are asking our visitors to wash hands regularly rather than use handgel which may cause damage to our collections.

Maria Merian and herpetology

Our December blog highights the work of Maria Merian as a herpetologist. Increasingly recognised for her work on insects, she was also interested in amphibians and reptiles but did not manage to publish a book devoted to them.

Where is 'Obaysch'?

A number of Fellows have noticed that Obaysch is missing from ZSL Library & Archives. The Barber Institute of Fine Arts have borrowed him for an exhibition so you can see him there along with the Frederick York album of photographs from around 1875 and a drawing of Obaysch by Joseph Wolf. He is on display as part of the exhibition Miss Clara and the Celebrity Beast in Art, 1500 – 1860 until 27 February.

Meanwhile in ZSL Library & Archives, we have a small display of items about Obaysch and have updated a blog about him
