My go-tos of love…
52 Weeks of Abundant Genealogy by Amy Coffin is a series of weekly blogging prompts (one for each week of 2012) that invite genealogists and others to discuss resources in the genealogy community including websites, applications, libraries, archives, genealogical societies and more. You do not have to be a blogger to participate. If you do not have a genealogy blog, write down your thoughts on your computer, or simply record them on paper and keep them with your files.
