The National Archives has a reference collection of 55,000 books, periodicals and directories on aspects of history (including local, family and military history), law, biography, genealogy and a wide range of reference material. Many publications relate to the documents held within the national archive itself. A growing number of electronic reference sources are also available.The bulk of the collection of published works is housed in the Resource Centre &#38; Library. A project to recatalogue these works from paper catalogues to an online computer catalogue has been continuing for several years. The Library is pleased to announce that this project was completed at the end of March and for the first time all Library holdings can be found in a single, online catalogue. The catalogue can be found at http://www.library.pro.gov.uk  NB: A lot of articles is cataloged as "pamphlets".
