New Review of U.S. Documents Masterfile 1774-2016
Please see this latest review of U.S. Documents Masterfile (formerly Public Documents Masterfile) in Information Advisor's Guide to Internet Research, June 2015
"We liked Paratext’s Public Documents Masterfile, and believe it provides another very good option for searching huge amounts of government information, supplemented by other public sources such as Data-Planet and Readex. We also like the fact that the database integrates such a credible and exact indexing method, which can make searching more precise compared to searching only on the full text."
