The WPA was responsible for a multitude of projects including building roads, bridges and other infrastructures. My own grandfather was part of the WPA in Arizona and helped pour cement for sidewalks around the town in which he lived. Humanities projects were also part of the WPA, hiring photographers, artists, and writers. The WPA was also responsible for documenting and cataloging resources vital to American history and, in essence, vital to the documentation of our ancestor's lives. One such project was the indexing of the 1920 U. S. Federal Census. Other indexes compiled by the WPA, include cemetery interments, military records, vital statistics, and newspapers.
Genealogists benefit from these WPA indexes and may not even know it. Microfilmed records and some online transcriptions originate from the work of WPA. According to Steve Paul Johnson's article on the WPA, entitled, "WPA Historical Records Surveys" at http://www.interment.net/column/records/wpa/wpa_history.htm, the US Genweb Census Project is a result of volunteers utilizing WPA census indexes. This census project can be found at USGenWeb Census Project.
To look for WPA interviews and records, consult state and university libraries, state archives, and state historical societies. Also consult the Family History Library Catalog and Google.
A keyword search on the term "WPA" in the Family History Library Catalog, www.familysearch.org, provides a list of 167 titles of microfilmed records that are the result of the WPA and its indexing projects. These records include indexes to cemeteries, historical records surveys, court records, and marriage indexes. One interesting entry is that of the Kentucky Medical History, a WPA project that includes health professional's biographies, information on medical schools, and the development of medical services in Kentucky since the Civil War. This is listed as "Kentucky medical history, WPA research project records, 1801-1940" in the online catalog. This resource does not circulate to Family History Centers; it must be reviewed at the Library in Salt Lake City.
In Arizona and other places, the WPA interviewed "pioneers" of the state. Arizona pioneer interviews are available through the Arizona State Library Archives and Public Records. An index of the names of those Arizona pioneers interviewed is found on Jean Carhart's web site at http://www.getnet.com/~jcarhart/arizona_wpa_pioneer_interviews.htm. I ordered a copy of my great-great grandmother's interview, which was about two pages long and detailed her life in early Arizona. A few of the interviews are online on Jean's web site, just look at the index and click on the hyperlinked names to get a sense of what information was included on the interviews. Another place to search for interviews is on the Library of Congress web site, American Life Histories, American Life Histories: Manuscripts from the Federal Writers' Project, 1936 - 1940. These stories are listed by state, and then indexed by first name. There is also a search engine available. You can then click on the name of a person and read their interview. States included in this database are Alabama, Connecticut, Florida, Georgia, Illinois, Indiana, Louisiana, Maine, Massachusetts, Missouri, Montana, Nebraska, New Hampshire, New Mexico, New York, North Carolina, Oregon, Rhode Island, South Carolina, Texas, Utah, Vermont, Wisconsin and Washington. The number of interviews vary greatly in this collection. There is only one for Utah and over 440 for Texas.
The Library of Virginia also has an online search engine to search through 1,350 life histories and 50 interviews with former slaves done by the WPA at http://ajax.lva.lib.va.us/F/?func=file&file_name=find-b-clas06&local_base=CLAS06
Other web sites include WPA interviews such as the web site entitled, American Slave Narratives: An Online Anthology at American Slave Narratives: An Online Anthology which includes a handful of interviews done with former slaves and includes a picture of many of those interviewed. This web site also includes a bibliography that would be helpful in researching further American slave narratives. The Special Collections section of the University of Arkansas has uploaded PDF files of transcripts of WPA interview forms for interviews done with 17 African Americans at http://libinfo.uark.edu/SpecialCollections/wpa/#Individual. There are also books that provide information on WPA former slave interviews. Consult Barnes and Noble (www.bn.com) or Amazon (www.amazon.com) and conduct a search for the term "WPA".
One source for records of people who worked for the WPA in Los Angeles is found through the University of Southern California (USC) Digital Archives at http://digarc.usc.edu:8089/cispubsearch/collectiondetails.jsp?collection=wpacards&recordid=wpacards-m85342&issubcollection=false . You can look at the 248 digitized employee census cards at this web site.
