Remember how in school, you would get together with a group of friends or classmate and worked together to study together. Everyone benefited from the the collaboration because you could discuss problems with the other members of the group until you had the topic mastered.
Until recently, at least as far as I'm aware, there was only one genealogy study group, the ProGen Study Group. Small groups are put together to study and learn from Elizabeth Shown Mills' Professional Genealogy: A Manual for Researchers, Writers, Editors, Lecturers and Librarians. The group works through the book together, with assignments based on the chapters covered. Assignments are shared with the group so everyone gets feedback. You can sign up by visiting the ProGen website.
Recently, a new genealogy study group was put together and it will be started soon. Headed by Tonia Kendrick of Tonia's Roots and Valerie Elkins of Family Cherished and Advantage Genealogy, the group will be studying two books, The Researcher's Guide to American Genealogy and The Source. The group will cover one to two chapters per month with monthly assignments based on the chapters covered. At the end of the 15 month study group, each member will put together a capstone project that encompasses all skills learned. You can sign up by contacting Tonia or Valerie.
