Appearances , 1999-2020, undated

This series is separated into three subseries: Appearances, Clippings, and Magazines. Appearances (1999-2020, undated) contains flyers, programs, and brochures of Troncoso’s many appearances at festivals and events. Of particular note is a souvenir from the 2003 Hispanic Scholarship Fund Alumni Hall of Fame Induction Ceremony that includes a video of the event where Troncoso won the Brilliante award.

Clippings (1975-2011, undated) predominately contains newspaper articles both about and by Troncoso and are arranged chronologically. The articles range from a 1975 piece about Troncoso winning a math competition (the medal he won is in the collection) to later reviews of his works and opinion pieces penned by Troncoso. There is one work of fiction included in the series: a story co-written with Christine Lehner in the October 2, 2003 issue of The Journal News.

Magazines (1997-2008) includes full magazine issues with articles about Troncoso and his work. These are also arranged chronologically.
