The Otilia Gomez Savala papers date from 1919 to 2012. The collection consists of digital content held in the Iowa Digital Library. The correspondence dates from 1919 to 1979 and includes documentation of her father's naturalization application process, his employment on the Work's Progress Administration (WPA) during the Depression and at Riverside Foundry in Bettendorf. It contains notices from Catholic Charities, as well as a letter from an attorney representing the Gomez family to the Uchtorff Company; the letter addresses the eviction notice the family received in 1950, and asks that the family be permitted to remain in their Cook's Point home until 1951.

The Cook's Point folder contains Savala's hand-drawn map of Cook's Point with a list of the families who lived there and where they lived. It includes a Spanish song about life in Cook's Point with lyrics by Otilia Savala and music by her brother Joseph Gomez.

Many of the photographs are of family and friends taken in Cook's Point during the 1940s. The newspaper clippings date from 1938 to 1989 and include articles relating to the history of Cook's Point and reports of the death of the Vasquez brothers, Albert and Ralph, in combat during World War II. An autograph book includes messages from school friends, and documents on Cook's Point include a list of residents, neighborhood plan, and poems about the neighborhood.
