Brian Houghton Hodgson seemed to be a keen compiler of lists, often of his specimens and drawings, and of his donations to the scientific and oriental establishments of his day. These were sometimes needed for transportation or storing of the articles itemised. This series comprises of 20 lists.

"Memo of Zoological Collections." List of drawings delivered to the British Museum by his father and to the Zoological Society in 1845. Further 4 copies of a list of "Distribution of B.H.H's. Zoological Productions." Also a rough note of zoological specimens. Handwritten, 6 pieces, 7 sides, dated 1845.

Hodgson used much of his time in both Nepal and Darjeeling in research, wanting to discover and understand about the architecture, languages, ethnography, religion, zoology and botany. He collected specimens and manuscripts, and had many drawings made, which he donated to many collections throughout Europe. He was also politically involved during his Residency in Nepal, and also later in England, when he continued to show an active interest in the Indian subcontinent, particularly regarding trade and vernacular education. These Personal Papers reflect these interests and are a record of much of his activity - Hodgson and his wives seemed to have a need to record all his successes. He was also a keen annotator of material, so that most of the printed material also bears his handwritten comments.
