What reference materials discuss any "known issues" in the microfilms of 1930 US Federal Census?

Question

I have been unable to locate some of the families I'm researching in the 1930 Census (for one example see my question What are good search techniques for finding people who have moved within the same geographical area?).

One well-known guide for US Federal Census information is William Thorndale and William Dollarhide's book Map Guide to the U.S. Federal Censuses, 1790-1920. However, this work does not include the 1930 Census. What other Guides exist for 1930?

Some basic information can be found at:

• The portal 1930 Federal Population Census at NARA
• The Ancestry.com Wiki (wikified from their reference work The Source) article on 1930 U.S. Census
• The FamilySearch Wiki article United States Census 1930
• The FamilySearch Wiki article on United States Census, 1930 (FamilySearch Historical Records)/Known Issues

Where else might I find information about other "known issues" with the 1930 US Federal Census? Could there be EDs or pages within EDs which did not get microfilmed?
