Series I. Research, contains research and the products of Brunor's research, relating to Rurutu and other Austral Islands and has been divided into three subseries. Subseries A. Manuscripts contains typed manuscripts, in various stages of completeness, written by Brunor. It is difficult to determine if some of them are drafts or final versions, as only a few of them are identified as either, and most of them do not appear to have a definitive beginning and ending, making it possible that they were intended to be part of a larger manuscript. At times it is difficult to distinguish between what Brunor intended to be a manuscript and what were just his notes; therefore, any items that could not positively be identified as either, were placed in Subseries B. There are some photographs interleaved throughout the manuscripts; however, most of the photographs can be found in Subseries B. Included in this subseries is a recording of Brunor transcribing one of his manuscripts. A number of manuscripts were damaged by black mold; these items were able to be photocopied, and the originals were disposed of. There are a number of typed manuscripts called "Victory in the Night". It is unclear if these are transcripts of Rober Andrew Robertson's 1875 manuscript "The Victory in the Night" with Brunor's commentary throughout, or if it is Brunor's manuscript. There are a number of photocopied manuscripts that are labeled by page numbers, it is not clear if these are all the same manuscript; however, they have been kept in the order in which they were donated. Original titles have been used when available.

Subseries B. Notes and Documentary Materials contains typed, handwritten, and recorded notes, film, and photographs. It is possible that not all of the photographs were taken by Brunor, as some say to credit the American Museum of Natural History, New York. The audio and film recordings remain restricted due to their formats, with the exception of five that have been digitized. A number of manuscripts and photographs were damaged by water and mold.

Subseries C. Secondary Sources contains secondary sources gathered by Brunor. These include photocopies of published articles and books,articles, pamphlets, and recordings. There is also a folder of miscellaneous notes.
