Barbara Hill of the California Genealogical Society posted this today to the Librarians Serving Genealogists mailing list:

“**ALL** of the DAR patriot information is online now, at the NSDAR website, and then some! You can even search by the names of descendants who were listed on an application. AND, their databases indicate when NOT to apply on a particular line because it’s probably not correct. It’s really quite fabulous, and renders all previous versions of the DAR Patriot Index obsolete. …”

The website referred to is the DAR Genealogical Research System. Say goodbye to those dear old blue books.
