Dear Yuqing Wu:
The book, Waldo Gifford Leland and the Origins of the American Archival Profession may be a good introduction to the history of archives in the United States.
You may also wish to review the following for relevant sources: Archival History Section of the Society of American Archivists: Bibliography of American Archival History.
I hope this information is useful. Best of luck in your research!
