Along with the subject files and notebooks is a large body of research material that does not have any apparent order. It includes several draft manuscripts, card indexes, research notes, tracings, drawings, and photographs. Topics include predynastic Egypt, Egyptian antiquities including scarabs and seals, ancient Egyptian religion as well as relating to research on sites in Egypt including copies of inscriptions, plans and drawings.

In a letter on the transfer of the Newberry collection to the Griffith Institute Archive in 1951 Dr I. E. S. Edwards (Keeper of Egyptian Antiquities at the British Museum) lists: Tracings of tomb inscriptions and decorations (packed in brown trunk); A group of texts and other material dealing with the Second Intermediate Period; and a large collection of "scholar's notes" on various subjects for the most part classified but in some cases merely labelled "Miscellaneous notes". It is this material which now constitutes this series. This material was arranged during previous archival processing according to subject and evidence of this work is still visible by the grouping and labelling of material.

It has been difficult to determine the date of much of this research material. Where a date range is provided it is often based on publications referenced by Newberry in his notes.
