Additional information for publishers
Legal deposit has existed in English law since 1662. Every new publication and every new edition of a publication, each of which may contain corrections, amendments or additional content, is liable for deposit. The requirement to deposit an item does not depend on its having been allocated an ISBN or ISSN, but they are used to identify items for deposit.
