five books of different colors representing the five national libraries in the United States: agriculture, transportation, education, medicine, and the Library of Congress“Today, we’re asking “How many national libraries are there in the United States?”

For most countries, the answer is usually one.

But the United States actually has five.

In addition to the National Library of Medicine, the other national libraries are the Library of Congress, the National Agricultural Library, the National Library of Education, and the National Transportation Library.

National libraries or libraries established by the government of a country serve as preeminent repositories of information. Often, they include numerous rare, valuable, or significant works and play an important role in the preservation of their countries’ cultures and intellectual traditions.

National libraries are commonly open to the public for research, and while members of the public may not directly check out items, they may be able to obtain them through interlibrary loan. National libraries are also increasingly making their collections available online, as copyright and digitization projects allow.”

OSTI, the science & technology portal of the U.S. Government

Agriculture,Commerce, Defense, Education, Energy, Health & Human Services, Interior, Transportation, Environmental Protection Agency, Library of Congress, National Aeronautics & Space Administration, National Archives & Records Adminstration, National Science Foundation, and the US Government Publications Office.

Terminology and thesauri might help in your information searches.

This site is a gateway to DOE collections at ScienceAccelerator.gov, global science via WorldWideScience.org, scientific research data as an open government initiative, and the OSTIblog.

Much of this, they declare, is outside Google’s purview — in the “deep web.”
