The majority of this collection was organized by Richard Lipsitz, Jr. under the title "Labor movement," from which the first series title is formed. This series is arranged primarily chronologically, largely comprising materials related to the American Federation of Labor and Congress of Industrial Organizations (AFL-CIO), the Western New York Area Labor Federation (ALF, a regional branch of AFL-CIO), Buffalo Central Labor Council (CLC, the Buffalo leadership of ALF), the International Brotherhood of Teamsters (IBT), the Coalition for Economic Justice (CEJ), and Industrial Relations Research Association (IRRA, now known as Labor and Employment Relations Association (LERA)). A description of the contents of each box provides a more detailed inventory of this large series.
