Publishers in the UK are required by law to supply one copy of each of their publications to The British Library, free of charge, within one month of publication. They are also required to supply a copy to five other libraries (see list below) within twelve months of the date of publication if requested to do so by The Agency for the Legal Deposit Libraries. In practice, most publishers supply these copies as a matter of course.

With a few exceptions (e.g. publications circulated only to members of a society), all printed publications come within the scope of legal deposit. Electronic publications (offline and online) will also come within the scope of legal deposit as regulations are introduced to implement the Legal Deposit Libraries Act 2003. Offline items (e.g. CD-ROMs) will be affected first. For full details of the Act, and exemptions, go to www.opsi.gov.uk/acts/en2003/2003en28.htm
