The Legislation subseries is arranged by legislative term and bill number. The subseries includes copies of the legislation introduced by Lesinski, correspondence about legislation, and supporting documents such as research or pamphlets about the topic. Legislation spans the areas of civil service, post office issues, retirement, and occasionally health or foreign policy issues.
The Committee files subseries are organized by committee name and then chronologically. The files include correspondence and reports from the committees on which Lesinski served. These committees include House Administration, which includes the subcommittees of elections and restaurants. Many of the files relate to his work on the Post Office and Civil Service Committee, and Subcommittee of the Census.
