Good and bad news here. LDS - FAMILY HISTORY CENTER REOPENED A FEW MONTHS AGO and HAS GOTTEN RID OF THEIR 1930 CENSUS MICROFILMS. BUT LOS ANGELES PUBLIC LIBRARY HAS THEIRS!
So much of the research I've done could not easily (or at all) be duplicated using Ancestry or other genealogy databases, which are as good at the typos. I TRIED!
BOTH LDS and LAPL WILL RELY ON ELECTRONIC DATABASES for the 1940.
But here is the link to the NATIONAL ARCHIVES SITE WHICH TELLS US THAT "The release of the 1940 population census schedules is approaching! It will be released digitally on April 2, 2012. (That is less than one year away!) You will be able to access all 1940 census records online at any of the public computer workstations at National Archives facilities, as well as from any computer connected to the internet."
Hey! I think the whole Mayan Calander/End of the World hoopla is bogus! I plan to live through it and be researching using the 1940 !
