THE NATIONAL YEARBOOK PROJECT
RootsWeb is host to the National Yearbook Project:
http://www.rootsweb.com/~usyrbook/.

National coordinator Judy White has organized the project by location.
Most submissions are from America, but foreign contributions are
welcome; Judy is especially trying to build items from Canada and the
British Isles.

Contributions can be individual photographs, indexes, and
transcriptions. A single page or an entire book can be submitted, as
well as links to external sites. Graduation and commencement programs
are also welcome items.

One of the highlights of the project is the classified ads. There are
people looking for yearbooks and others selling. Maybe you'll get
lucky and find a match.

U.S. SCHOOL YEARBOOK DATABASE
Ancestry.com has digitized yearbooks into the U.S. School Yearbook
database. If you don't have a subscription, try your local library for
access. To date, there are more than 1 million names indexed. The
collection includes books from middle school, junior high, and high
school.

Ancestry.com encourages submissions, so if you are inclined, send a CD
with images scanned at no less than 300 dpi. It should include the
front and back covers, as well as all interior images. If you are
unable to send a CD, contact them for other arrangements.

From RootsWeb:

So you just found your ancestor on the 1860 census, and you see the
value of his personal estate listed as $500. "That's great," you
think, "but how much is that today?"

A site called Economic History can help you figure that out. Use their
calculators and other resources to get an idea of whether your
ancestor was a prince or a pauper.
