United States history includes the history of peoples and countries of all the Americas since their initial human settlement, not solely the United States and its colonial antecedents. Nonetheless, a bias toward North America is a reality in the tools for discovering the scholarly literature, and primary sources in the library's physical and online collections are almost entirely from the USA.
Researchers interested in Latin America, the Caribbean, and the history of the Atlantic or Pacific basins should also consult the resources in the world history subject guide. For scholarship regarding the pre-colonial history and prehistory of the Americas, see also the anthropology subject guide.
Tech's University Libraries seek user input about possible purchases of online resources; October, February, and April are the primary trial months. Let us know how (if...) a trial fits the research, teaching/learning, and public service missions of the university. Share your judgments through the short survey linked to each trial blurb and/or more detailed remarks in an email to a subject librarians.
All active trials are listed in a sidebar on the Databases A-Z guide, usually including their expiration dates and links to online user evaluation surveys. Here I list current trials of likely interest to the departments I serve.
