We want to provide a trustworthy [[encyclopedia]]. It's a good idea
to let the reader know where we got the information, so they can
decide how reliable that source is. [[NASA]] is a good source for
astronomy and space travel. The [[United Nations]] may or may not be a
reliable source of economic, political or scientific data.
Also, as a matter of [[scholarly ethics]], the [[academic community]]
considers it important to be open about how much of any work you wrote
yourself, and how much you copied from others; see [[plagiarism]].
Whatever federal information the U.S. government creates and releases into the [[public domain]] is really our stuff (as taxpayers). There is no law requiring credit to be given for copying public domain writing; by definition it is "ownerless" (public) property.
However, it is usually a good service to our readers, if we cite the
agency and/or author of public domain works. If only because it makes
the article more trustworthy. But also because it gives the reader a
hint of where to go for more information.
