In a letter relating to the accession of Newberry's collection to the Griffith Institute Archive in 1951 Dr I. E. S. Edwards (Keeper of Egyptian Antiquities at the British Museum) lists 'Files containing notes on individual subjects (mainly in filing cabinets)'. This series is made up of files which are all consistent in appearance and contain notes on individual subjects. Each file tab is labelled with a subject heading and contains research notes. Some of the files contain research that has evidently been done at different times but subsequently gathered together. For example files contain pages cut from notebooks.
Some organisation of this material was done during previous archival processing. Unfortunately it is not possible to know whether the contents of the files are as they were when received or whether related material has been added to these files from elsewhere in the collection.
There is evidence in Newberry's correspondence that in the period after the Second World War to the end of his life in 1948 Newberry was organising his research material in preparation for a general publication on ancient Egyptian history and archaeology. It is possible these files were created by Newberry in preparation for this publication and as such form a distinct series within the collection.
