This series is divided into three sections: "General Correspondence," "Correspondence of Others," and "Family Correspondence." "General Correspondence" is arranged alphabetically by the name of the writer of the letter, by the name of an organization, or by topic. Topics not previously mentioned include "The Arctic Club and Arctic Exploration" and "California Petroleum Controversy." Letters written by William Henry Brewer are filed under the name of the person to whom the letter was addressed.
The following is an inventory of the materials which were too large to fit in the regular manuscript boxes and were therefore placed in a folio. Each item is also listed elsewhere in the Register, in its appropriate series and box, accompanied by its corresponding Folio number.
This series is divided into six sections: "Certificates," "Correspondence," "Notes," "Printed Matter," "Records," and "Legal Documents." "Correspondence" is generally with people related to Brewer who are interested in the Brewer Genealogy. "Notes" consists of material collected by Brewer from various sources. Most of the material in "Notes" was added to the material in three volumes entitled "Records." The "Records form a fairly complete genealogical history of the Brewer family in America. Most of the "Legal Documents" are copies of family wills. The material in this series is arranged alphabetically within each section.
