Born in Puerto Rico, Arnaldo J. López serves as the Development Officer at Pregones/Puerto Rican Traveling Theater (PRTT). He holds a Ph.D. in Latin American Literatures and Cultures from New York University and is an avid advocate of the arts. This collection features an array of zines, ephemera, comic books, and other archival material he collected in his lifetime.

This collection documents Book Are Nice and the organization's involvement in the literary culture of Miami. The collection currently includes materials from two editions of Pages & Spreads, a series of pop-up reading room events that Books Are Nice has helped organize.

The O, Miami collection holds memorabilia associated with the literary organization and their events and publications. The materials document many of the inventive techniques used to promote poetry during their annual O, Miami Poetry Festival, including poetry parking tickets and poems in the form of lottery scratch off tickets. Other events documented include the organization's visiting writers series, and their collaborations with Pages and Spreads, another local literary organization. The collection also includes chapbooks/zines that collect poems and writings from local Miami writers.
