This small collection contains manuscripts of stray archival materials found loose within the working library collection. Included are: letters and cards (from Betjeman himself, and also to Betjeman from family, friends, literary and other acquaintances including aspiring poets, publishers and fans); draft articles and reviews, drawings; notes; and manuscript poem drafts/fragments (mostly unpublished), the majority of which have been partially (because of the illegibility of his handwriting!) transcribed and listed. Also included are original and copy typescripts and manuscripts of unpublished works (mainly literary, but also including some photograph albums) by friends and acquaintances of Betjeman, many of them signed by the author - these are fully transcribed.
Many of the books in the library have also been heavily annotated by Betjeman (with jottings, rough notes, poem fragments etc.), and these inscriptions have also been partially listed and transcribed.
