The Wilder Wylie Collection was donated to the University of Missouri-Kansas City in June 1990.

Housed in LaBudde Special Collections, the manuscript materials consist of radio scripts for KIDO-NBC, the Bob Hope Show, various radio plays produced by the National Broadcasting Company (NBC), radio commercials for Borden dairy products, as well as scripts for several television shows. Many of these scripts are written by Wilder Wylie. Among the KIDO radio programs are nearly all the scripts for Down Memory Lane with Kathryn Kane, Fashion Club, and KIDO Showcase. There are over 30 other scripts, as well as four KIDO program schedules from February 1946 to January 1948, fan letters to KIDO, and correspondence between KIDO and NBC. Most of the collection's radio scripts produced by the Continuity Department of KIDO-NBC bear the initials, WW (Wilder Wylie). Another major component consists of scripts for the Bob Hope Show. Scripts from 1949 were sponsored by Lever Brothers Company while those from 1953 were sponsored by Jell-O. Also included is a sizable collection of 'live' Jell-O commercials written for Bob Hope. The collection also contains various radio plays produced by NBC between April 1949 and October 1950. Several of these productions were created by Young and Rubicam, a media production agency for whom Wylie worked. Among the highlights of these scripts are the shows of Jack Carson and Bing Crosby. There are also scripts for Borden radio commercials produced by Young and Rubicam probably between 1949 and 1955. In addition, there are several television commercials for the Borden Company and three broadcast schedules. Materials also contain television show scripts, promotional information of CBS and NBC, as well as fifteen booklets entitled Round Table, a radio discussion on NBC in 1942 and 1946, published by the University of Chicago.

Housed in the Marr Sound Archives, the audiovisual materials consist of 41 16 inch records of a variety of KIDO programs between 1945 and 1947. Many of these programs were written by Wylie Wilder. Accompanying scripts may be found in the Wilder Wylie Collection in LaBudde Special Collections. The "KIDO Showcase" makes up the largest portion of this collection, with all or parts of 15 shows spread across 20 discs. Other programs included in the collection are the "Agen show" "Archie Andrews," "Ohmstead Playhouse," and "Saturday with the Sepples." There are also three discs with recordings of Nat King Cole, and discs with advertisment recordings.
