Visiting the Library

Opening hours

The RAS library is open by appointment only on Tuesdays, Wednesdays and Fridays from 10am to 1pm, and from 2pm to 4.30pm.

Visitor access

Fellows, Friends of the RAS and other visitors who wish to use the RAS Library and Archives will need to make an appointment by contacting or by phoning +44 (0)20 7292 3963.

If you wish to visit the library and ensure that materials you want to consult are available, please make the appointment by the following cut-off times:

  • By midday on Monday for a Tuesday visit
  • By midday on Tuesday for a Wednesday visit
  • By midday on Wednesday for a Friday visit

This will give us time to check that material requested is available to consult, and fetch it in advance of your visit.

If you do not make an appointment, it will not be possible to admit you to the building. 

You can make an appointment by emailing or by phoning the librarian on +44 (0)20 7292 3963. 

You can search most of our collections using the catalogues online, and we are happy to answer any questions about what we hold in the library and archive.

If you are not a Fellow or Friend of the RAS, please bring identification with you so that we can register you as a reader. 


We are happy to answer general enquiries about our collections and the services we provide. Before you contact us, you might find the answer in our book and journal catalogue or our archive catalogue. For details of these and other sources of information on astronomy and geophysics, and biographical information on past Fellows, see Help with your research.

If you can't find the answer to your question on the website, contact the librarian. We can't carry out detailed research for users but will point you in the direction of alternative sources of information if they exist.
