This is a brief guide to manuscript material, typically archives or collections of papers, that is known by a name not used in the online or published catalogues. It also lists material which forms collections of special interest and material that is in an unexpected location or microform format.
Only the main group of papers is given and there may well be other groups of related material (particularly related charters) which can be found by consulting the Manuscripts Online Catalogue.
DPB refers to the printed books collections.
SPSI refers to Social Policy Information Service.
RBMRR refers to the Rare Books and Music Reading Room.
This information is derived from British Library Manuscript Collections Reference Guides 1 & 2, Principal Large Collections and Selected Smaller Collections and Microforms, 1998, which can be found in the Manuscripts Reading Room.
