Casimir Lewy Library

Welcome to the Casimir Lewy Library

The Casimir Lewy Library provides support for philosophical study, teaching and research in Cambridge. The book collection comprises more than 17,000 volumes, focusing on Western analytic philosophy. The Library provides a pleasant, quiet study environment, with friendly library staff to help you make the most of the resources available.

The Library is named after Casimir Lewy (1919-1991), University Reader and fellow of Trinity College. He was an inspirational teacher, whose passion for clear thinking and logical rigour still echoes through the Faculty.

See our LibGuide for more information about Philosophy collections available in Cambridge. 


Information about available library services and Coronavirus (COVID-19) - last updated Tuesday 19 January 2021

The physical library is currently closed to users but we're still available online to assist you in accessing the resources you need for your teaching, learning and research this term. Email us at and we will do our very best to help.

The following zero contact services are available.  See for details of other services on offer from the University, Faculty and Department Libraries: 

  • Click and Collect for those still resident in Cambridge: book appointments to collect items requested online 24 hours in advance between 10am & 11am and 3pm & 4pm, Monday to Friday.  This is a joint service offered in collaboration with our colleagues in the MMLL Library.  The collection point is now at the north entrance of the Raised Faculty Building, to the left of the main reception area.  To book a click and collect slot go to  Please note: this service is designed to give access to resources that aren't otherwise available electronically or where there is a specific need, rather than preference, for the print to University members still resident in Cambridge.  You must not travel from outside the local area to use this service.  If you have a particular need to access a print copy and are not resident in Cambridge please the details and we'll do our very best to help.
  • Scan and Deliver and printouts of electronic legal deposit material: if there is one chapter or 10% (whichever is greater) of a print book you need for teaching or learning purposes please the details.  We may be able to make a scan available to Philosophy staff and students via Moodle.  Subject to copyright permissions and limits, the University Library may also be able to make and email scans of print material and print and post extracts from material only available via the electronic legal deposit machines.  See for further details.
  • Book recommendations, Phil the Gap!: please continue to send us your book recommendations by emailing us the details or completing the online form at - we'll buy ebook copies where we can, subject to cost and availability, to make them as widely accessible as possible.
  • Book returns: your books should continue to automatically renew and it shouldn't be possible for them to be recalled by anyone else so you don't need to worry about returning them this term.  If you are resident in Cambridge and need to return books, please put them in the Sidgbox next to Lady Mitchell Hall and we'll take them off your account as soon as we're able.  However, please be aware that if staffing levels mean we can't regularly empty the Sidgboxes we may need to lock them at short notice.  For more information about returning books see

The above services may be subject to alteration in response to changes to current Government and University guidance and staff availability. We will monitor and review them in line with ongoing advice and will seek to increase services when it is safe to do so. This means we may have to change or discontinue some services at short notice. Please check this page for further updates before planning any trips to the physical library.

Thank you for your continued patience and understanding during these unprecedented times.
