Most correspondence is incoming, though occasional files also contain outgoing correspondence from Joseph Frank and his wife, Marguerite Straus Frank. A small group of family correspondence between members of Frank's family is also included following the alphabetical correspondence, including condolence letters addressed to Marguerite Straus Frank following Joseph Frank's death.

This series represents Rossi's scholarly and literary output over a span of nearly five decades. Among the most compelling materials are a group of notebooks which he called "Cuadernos," in which he recorded almost daily diary entries over a thirty-year period. Other materials include drafts of writing, notes, and photocopies of published articles.

The correspondence files reveal the depth and breadth of Rossi's involvement in a variety of intellectual circles in Mexico and abroad. While the format may have changed over the years from typed or handwritten letters to faxes and emails, the regularity and discipline with which Rossi corresponds with his friends and associates does not at all diminish. If anything, it even flourishes in later years.

Includes materials that Rossi considered important, such as founding documents of Vuelta and two items related to his ancestor, the Venezuelan general José Antonio Páez [1790-1873]. This series also includes several scrapbooks that were assembled around the time of Rossi's death.
