Here's the latest from FamilySearch:
"The Record Search pilot has added 72 million new names to its Mexico Baptism collection online. The collection was transcribed from Mexico parish records dating from 1659 to 1905, and is not necessarily complete for any particular place or region. It also includes records from the Middle America Vital Records Index--Mexico that was published in 1999 on CD only.
The newly expanded database can be searched for free at http://pilot.familysearch.org. The data was transcribed by FamilySearch's impressive force of volunteer indexers worldwide (see www.familysearchindexing.org). Volunteers donate a little time each week or month transcribing select information from digital images of original source documents using FamilySearch's online indexing utility. Anyone interested in joining the global, community-based indexing initiative, or wanting to see what projects are currently being indexed, can do so at www.familysearchindexing.org. "
