|Description||Blackett's folders of working notes and papers are of a very miscellaneous composition. An attempt has been made in the list below to present them in a chronological order, but since many of the folders contain a wide range of material of differing dates, this ordering is of necessity somewhat artificial and incomplete.|
Some originally very bulky folders have been split into several smaller folders for ease of reference, eg B.22-25, B.35-37; in some cases, manuscripts and drafts for lectures have been removed and listed separately (see the introductory note to B.84-131).
Some of the papers refer to measurements and observations recorded in laboratory notebooks. It has not been practicable to cross-reference such cases to the notebooks listed above (B1-21), since many of Blackett's notes refer to books which are missing from the sequence.
Some of the notes are written on the verso of examination scripts, others are on specially devised forms for the recording of data. All notes are manuscript, and in Blackett's hand unless otherwise indicated; other hands are identified where known.
All correspondence found with these working notes has been left in the folders.
