There are a plethora of freely available primary source collections online. I have listed a small selection of immigration resources, divided by regional and national collections, below .
CSU students, faculty, and staff can use their RamCard at the Poudre River Public Library District to check out and access PRPLD’s impressive collection of material.
The CSU Libraries and Poudre River Library district does not subscribe to HeritageQuest, a powerful database that provides access to U.S. Federal Census, family and local histories and city directories, Revolutionary War records, Freedman's Bank records, genealogical periodicals and selected congressional documents and reports from the American State Papers and U.S. Serial Set.
If you have access to another public library, please check to see if they provide access to this tool.
