This collection consists primarily of correspondence written by Homeboy clients and family members to Homeboy founder Father Greg Boyle. Many of these clients were gang members incarcerated at the time of their writing. They ask for assistance, describe conditions within the prison, and discuss their alleged crimes and potential parole.

The administrative records consist largely of copies of thank-you letters sent to donors. There is also information on the physical plant of Homeboy Industries and on the California Youth Authority. Father Boyle's personal papers consist largely of correspondence, photographs, and material regarding his book Tattoos on the Heart. The collection also includes a number of DVDs and CDs.
