Most of the records pertain to the production of the Heraldette, an internal paper for the employees of the Miami Herald. Photographs and some negatives of mostly unidentified staff members at work and company sponsored social events make up the bulk. Also includes art work and a mostly complete run of the paper from its beginnings as the Slick Edition.
Financial records and company documents contain shareholders' and directors' minutes, insurance policies, mortgage deeds, contracts, leases, promissory notes, abstracts of titles, advertising rates and statistics.
Personal records of John S. and James L. Knight include biographical information, editorials, and photographs with prominent public figures such as John F. Kennedy and Richard Nixon.
A group of photographs of Dr. Martin Luther King, Jr., completes the collection. Some of the images were shot in Miami by Miami Herald photographers, but most are wire service shots from the Associated Press.
Some events are recorded on VHS tapes.
