These include the Mexican Civil Registration records and the Catholic Church parish records which are searchable by name now, which makes it so much easier; I remember having to painstakingly search the Mexican Civil Registration Records image by image just a few years ago! Some of the Church parish records still need to be searched image by image though. They also have the 1930 Mexican Census, and more!
The Research Wiki is a fantastic tool on FamilySearch .org, that will help you with your research. From there, you can search records, get research advice and tutorials, Spanish handwriting tools, a Spanish genealogical word list, dictionaries, Mexican history, and more! I did not learn about the Wiki until I took a trip to Salt Lake a couple of years ago, not to mention it is fairly new. The FamilySearch Wiki started back in 2008, but did not have nearly what they have now!
