EXTHen II-1970sDocuments and objects extracted from various record series
This is an artificial accumulation created by the Public Record Office during the twentieth century to cater for documents and objects extracted from records following transfer to the Office, primarily as a preservation measure. The most common reasons for extraction were that the item when opened exceeded the overall size of the document of which it formed part, or of other documents in the series, or that the item was of a different physical format from the document of which it formed part, or other documents in the series.
Initially two EXT series were designated; EXT 1 was entitled Large Document Extracts, Kew, and EXT 2 was entitled Safe Room Extracts, Kew. Subsequently six further EXT series were created (EXT 3 to EXT 8).
EXT 3, EXT 4 and EXT 5 contained documents from series that moved to Kew in 1977, while EXT 6, EXT 7 and EXT 8 contained documents from series that stayed at Chancery Lane between 1977 and 1997. Additions were, however, made to EXT 1 until relatively recently as well as items being placed in EXT 3, EXT 4 and EXT 5. It is not intended to add any new items to any of the EXT series.
