The Union Cemetery Historical Society was organized in 1984 under the guidance of the Kansas City, Missouri, Parks and Recreation Department. It's purpose is to collect data about historic Union Cemetery and to gather biographical data about the people buried there. Due to those efforts, the society published Tombstone Inscriptions in 1986. As stated in the title, this hardbound book lists many of the people buried in the cemetery.

The Society also published a series of 10 pamphlets containing collections of obituaries and biographical sketches gathered mostly from microfilm copies of old newspapers. In some cases, these obituaries and/or death notices are the only record we have of an individual being buried in Union Cemetery. Thombstone Inscriptions and the pamphlets are available for sale in the sexton's cottage.

The files in the cottage provide rapid access to the cemetery burials. They contain a wealth of genealogical  and biographical information collected by members and/or donated by visitors.

The Union Cemetery Historical Society also publishes a quarterly newsletter for its members. The Epitaph keeps members informed about Union Cemetery and Union Cemetery Historical Societies efforts to keep it an historical treasure for future generations.

The sexton's cottage is open from 9 to 11 a.m. Wednesdays and from 1 to 3 p.m. Fridays.
