Here is some information on the library space so you can orientate yourself within it and see what it looks like before you visit.
Detailed access guides for University buildings are available via the University of Cambridge AccessAble site, including the main Department of Chemistry Building, Centre for Molecular Informatics (which houses the Chemistry Library), and the Chemistry of Health building. These should give you all the information you will need including photos and descriptions of our library and department spaces.
The Chemistry Library also has a virtual tour in the form of 3.5 minute video which will give you a good idea of how the physical library space is usually organised:
You can see a 360 degree image of the library (click on the 'Explore 360' link and use the arrows to view and move around the space, and click on the 'i' buttons for further information).
Other study spaces available in Cambridge and beyond
There is also the Accessibility and Disability Resource Centre's Building Access Guide which assists anyone who wants to find the best way round the university and colleges (including some of their libraries).
Try using SpaceFinder to locate study spaces available in Cambridge Libraries and other venues around the city.
AccessAble gives you accessibility information for over 10,000 venues across the UK including shops, pubs, restaurants, cinemas, theatres, railway stations, hotels, colleges, universities, hospitals and more.
