42. USA.gov

Do you remember the Consumer Information Catalog, published since 1971 by the U.S. General Services Administration?  Free copies were often available at public libraries, and the catalog listed free and/or inexpensive government publications.  Well, their Final Edition was the Winter-Spring 2016, and ordering from it was discontinued on September 15th.

However, the publications formerly available there can be downloaded or ordered at http://USA.gov/explore .  I typed the word disaster into a search engine on that site that generated twenty documents on that topic. Typing emergency generated an overlapping, but different set of twenty, and adding the word communications to either search resulted in different document sets.

So give usa.gov a try sometime.
