Topical files
The Topical Files, contained on microfilm Rolls 1-42, are arranged alphabetically. Much within them is simply reference material saved on a variety of subjects tied together by a connection with the open shop. Within the topical files, however, are the files of the National Erectors' Association. Also there is a wealth of detailed information about labor conditions in specific locations, some of it assembled by paid agents. Information about specific locations is usually fragmentary. Finally, under the heading "Southern Pacific Railway Company" are several folders giving a generally complete view of how the Foster Agency carried out a specific assignment.
