CERN Accelerating science

The theses collection aims to cover as well as possible all theses in particle physics and its related fields.
The collection starts with the thesis of Feynman, defended in 1942, and covers now alltogether more than 3000 theses. Most of the documents are held as hard copies, theses from later years are available electronically. (Note also that many theses are not physically held by the CERN Library.)
