* An archived instance is a single snapshot or copy of a title that has been added to the archive. Many titles are copied into the archive more than once to capture changing content, for example, when serial titles add new issues. Each new copy of a title is referred to as an 'archived instance'.

Note: The archive comprises three master copies (preservation, display and metadata) stored on the Library's Digital Object Storage System (DOSS). In addition to the master copies a copy for display purposes is maintained on a web server and it is from this single copy that these figures are derived. Therefore these figures should be seen as indicative rather than inclusive.
