I found this short book to be a helpful addition to anyone researching their family history's reading list. Of course, it is not designed to be THE beginning book someone might read when learning to research their genealogy, but it supplements one the included topics: family records, libraries, and church records. Even these topics are not covered definitively, but each topic is introduced with research strategies and examples taken from the author's own family research (I love case studies and examples). I sometimes felt he left out something or was slightly wrong about something (the early precursor to today's United Methodist Church was the Methodist Episcopal Church, NOT "Methodist Episcopalian"), but the techniques he describes should aid researchers to develop their own search strategies and find some sources.
The edition I read was copyrighted in 2012, so includes many examples of online searches and sites to visit. Some of that information is now outdated, but one can pretty easily catch up with the changes using standard search techniques.
This volume is just one of the Quillen's Essentials of Genealogy series. I think I'll check out some of the others. I've been researching and teaching genealogy for over 50 years, but it always seems to help review some things, find out new information, or be reminded of something I've missed in my research.
