Today's church record collection is a good example of being open to the possibility of records being in any number of places. In this case, records for the Provo (Utah) Community Congregational Church are archived at the University of Utah. I found this collection on the Mountain West Digital Library website.
According to the page for this collection, "The Provo Community Congregational Church Records (1883-1986) consist of the records of various church-sponsored organizations, board and committee materials, Sunday bulletins, minutes, financial records, correspondence, histories, and miscellaneous papers. The Provo Community Congregational Church was one of the earliest churches organized in the state of Utah."
There's many great records here including church bulletins from 1925-1982, yearbooks, baptismal records, and a Pastor's diary.
In some cases, church records may be donated and kept as a manuscript collection at an academic library. Fourteen linear feet of documentation from this church is open for research by the public but it is recommended that you call 24 hours prior to your visit to the University of Utah library.
So the next time you are looking for church records, consider a nearby academic library as a resource.
