Matt Baker's subject files are chronicled in this series through a mix of newspaper clippings, e-mail correspondences, letters, conference briefings, information packets, whip counts, floor remarks, bills and amendments, and other forms. Baker's earliest subject research involved cases pertaining diabetes in school.

The contents found in this series are not organized purely by chronological date, but still take place within a relative time span ranging from 2011 to 2016. All contents have been organized by original order as they were found upon donation.
