Ancestry.com has added to its growing collection of school yearbooks. This collection is well-worth checking out because you never can tell what schools have contributed to the collection: the size of the community or the school does not dictate what institutions are represented.
This from Ancestry: "While yearbooks may not provide information about the vital events that are usually associated with genealogical research, they do provide other information about individuals' lives. This information helps place people in historical context as well as provides detail that helps turn individuals, sometimes only known by names and dates, into actual people."
To find the collection, search the catalog with the key word "school." With recent new additions, the collection has over 200 million records.
Ancestry is a subscription service, but you can get to it for free from your public library.
