If the Caltech Library collection does not have a book or subscribe to an article that you'd like, you can request it through Docuserve (Interlibrary Loan). In February 2015 the Docuserve fee was waived so it is now free. You can email me directly if you'd like a book to be purchased for our collections or use this form.
