I maintain a site I call "History at the Department of Labor" ("History@DOL" for short). It focuses on the Department but also deals with labor history. For example, it includes the full text of the Department's 1976 book, The American Worker, a history written by distinguished academic labor historians for the national Bicentennial. There are also articles from the Department's Monthly Labor Review, a few conference papers (mine), historical documents by or about the Department, and much more. A highlight is the 1965 Moynihan Report, the only web copy, as far as I know, of that still controversial document. Daniel Moynihan was an Assistant Secretary of Labor when he put it together.
The URL for History@DOL is: www.dol.gov/asp/programs/history/main.htm.
