Familysearch Indexing of Digitized Films
In case you didn't know, the LDS project for digitizing films is going much faster than anyone expected. They have now begun projects where volunteers can extract documents online using special software that you can download. I did it tonight just to see what it was like and it is amazingly simple to do. It looks like it is mostly the 1900 census for the moment. I think this has to do with the standardization of the documents which makes it possible for volunteers with minimal or no training to find the information and enter it correctly.
