Keeping up with sites that regularly update or add more information can be time-consuming. Some sites send out press releases about new databases and improvements. Others do not.
Personally I’m waiting for a few counties to be added to the online chancery records at the Library of Virginia, some records to be added to the free War of 1812 pension file here at Fold3.com, and newspapers to the Library of Congress “Chronicling America” collection. I may be waiting a while.
I’ve have a list of things I’m waiting for on various sites that are “in progress” and I’ve decided to check monthly (or even less often) to see if new to me items are there. There’s no need to check daily or weekly and a list keeps me more organized and helps me not to forget all the items in which I have an interest.
