Series I. Land Deeds and Titles contains land deeds and abstracts of titles of land owned, bought, sold, or managed by David Pingree, E. S. Coe, or their agents. Some of the deeds and titles have been arranged alphabetically, others have been arranged by location; the documents have been left in the original arrangement in which they were deposited (alphabetically or by location). Subseries A. Deeds and Abstracts of Titles contains land deeds and abstracts of titles of land owned, bought, sold, or managed. The first set of deeds and abstracts of titles have been arranged alphabetically and an index for these can be found in the box 1, folder 1. Within these alphabetized deeds and abstracts of titles, letters with larger amounts of materials have been further divided geographically. Before the abstracts of titles and memos start, there is a folder titled "Summary of abstracts of titles and memos" which contains a detailed description of what can be found within the abstracts of titles and memos. Subseries B. Deeds and Abstracts of Titles Indexed in 1953 contains an alphabetical list of copies of deeds and abstracts of titles that were indexed in 1953. These materials were not integrated into the other deeds and abstracts of titles because of their having been indexed; they are arranged in alphabetical order. It is unclear who indexed these records or why. Subseries C. Abstracts of Titles and Memos contains abstracts of titles and memos from land in Northern Maine, which was indexed by location. It is unclear who indexed these or when it was done.
