Covering 137 Connecticut towns and comprising 14,333 typed pages, the Barbour Collection of Connecticut birth, marriage, and death records to about 1850 was the life work of Lucius Barnes Barbour, Connecticut Examiner of Public Records from 1911 to 1934. This present series, under the general editorship of Lorraine Cook White, is a town-by-town transcription of Barbour's celebrated collection of vital records, one of the last great manuscript collections to be published. Each volume in the series contains the birth, marriage, and death records of one or more Connecticut towns. Entries are listed in alphabetical order by town (also in alphabetical order) and give, typically, name, date of event, names of parents, names of children, names of both spouses, and sometimes such items as age, occupation, and place of residence.

The fortieth volume of the Barbour Collection covers the aforementioned four additional Connecticut towns, altogether referring to 29,500 early inhabitants.
