The New Hampshire Old Graveyards Association has posted lists of names of cemeteries and their locations for most New Hampshire towns, including Lebanon. By clicking on the name of a cemetery, the researcher’s web browser is redirected to a topographical map showing the location of the cemetery.
Gravestones transcriptions have been made for some stones in Lebanon cemeteries beginning about a century ago. None of these transcripts is complete and each contains some errors.
The two published volumes deal with early Lebanon residents buried in some of the smaller cemeteries at the edge of town:
Hills, Thomas. 1910. Three Ancient Cemeteries in New Hampshire, Near Junction Boundary Lines of Lebanon, Plainfield, and Grantham. Boston: D. Clapp & Son. (64 pp.)

These volumes are available for perusal at the Lebanon Public Library (East Park Street at Bank Street on Colburn Park), the NH State Library (30 Park Street, Concord, NH), and the NH Historical Society (30 Park Street, Concord, NH).
The NH Historical Society has a copy of a typescript of gravestone readings from Glenwood Cemetery in Lebanon compiled by Gertrude Rock in 1966. This copy of a mimeograph is 28 pages and is located in the Vertical Files in the Historical Room.
