Upon Bayh's election in November 1962, Robert Pitchell, associate professor of government and associate director of Indiana University's Bureau of Government Research, arranged to take a year's leave to oversee the legislative work of Bayh's office. When Pitchell left in February 1964 to become president of Roosevelt University, Clark F. Norton, professor of political science at DePauw University, became de facto legislative director until 1971. The ramifications for Indiana of any piece of legislation were foremost in the minds of Bayh and his staff, leading to a great deal of overlap between files kept by Indiana Department staff members and those assigned to the Legislative Department and often to intermingling of legislative, committee, and Indiana concerns within a given file.

Where known, the staff member who created a file is indicated by initials in parentheses beneath the heading in the center of the folder tab (also noted in the folder list in brackets). Key staff members who contributed to the legislative work are listed below in roughly in chronological order. Their files of memos and correspondence are to be found in the Legislative Administration subseries of the Legislative Activity and Administration series as Staff Files and Staff Memos.
