The Canonical Stack—book sculpture by Christopher Evans and Issam Kourbaj (photograph, David Webb). The sculpture was an arrangement of books, mainly from the Haddon Library, and was photographed in situ there on 8 March 2008. All the books are now back in their normal use.
The Haddon Library serves the staff, research students and undergraduates of the University, together with members of the Cambridge Antiquarian Society. Staff and students of other Universities are welcome to read here, on production of evidence of academic bona fides. Other visitors should enquire in advance.
You can donate to the Haddon Library online. Or, if you prefer, read the library's appeal and then donate online. Start by clicking the 'Give Online' button above. Thanks!

Cambridge has plenty of other libraries you might find helpful – the college libraries, the faculty and departmental libraries, the central Cambridge University Library (always called the UL). See the Cambridge Libraries Gateway. Libguides shows resources available in particular subject areas, and Spacefinder shows spaces where you might want to work, in libraries, museums, common rooms, coffee shops, pubs &c. A basic rule of thumb is this:
* college libraries are for college members only
* faculty and departmental libraries admit most Cambridge University members, but have a variety of regulations and opening hours
* the UL admits all members of the University. Undergraduates may borrow there — five items at one time, with a loan period of two weeks.
Try the University’s electronic books as well.
Most of those libraries are catalogued online. Help in the use of that catalogue, including how to restrict your search to particular libraries, is on Libguides.
If these web pages don’t take you to what you’re looking for, ask a member of the Haddon team. Ring 01223 333505 or email haddon-library [at] lists.cam.ac.uk .
