Two very useful original collections are located in the library. County tax rolls (mostly personal but some land) from 1900 to 1939 are housed in the library. These can document when and how long a family lived in the county; they also tell something about the lifestyle of the family. Abstracts of land holdings prepared by McIntosh and McIntosh of Collins. This firm worked with oil companies and traced ownership of land back into the 19th century. Many useful pieces of information can be found in these abstracts.
The society is currently working on a name index for the Covington County files. The Society Library and Reference Collection in the Seminary Depot are open to the public for research by appointment.
