The Articles & Preprints collection aims to cover as far as possible the published and pre-published literature in particle physics and its related technologies. The collection contains something like 400,000 documents, out of which about 50% can be accessed electronically. The documents originate from articles published in journals, preprints, technical reports, conference presentations, scientific committee documents and theses - all comprehensively indexed by the CERN Scientific Information Service. The collection starts, comprising only the most important documents in the first decencies, from the mid of the 19th century. The full coverage starts from 1980 onwards.
