Mountain Dew Southern 500 Interactive CD, 2002

Memorabilia concerning drivers, speedways, and sponsors make up the majority of the collection, including media kits and race statistics. Media kits are often distributed by advertising agencies, contracted by either race teams or sponsors to highlight either a driver or their product. The kits usually contain paperwork detailing the career or objectives of the driver and/or team, and sometimes contain photographs or promotional cards. The majority of the media kits date from the 1990s to 2008. Race statistics sheets are distributed either by the track, or NASCAR's statistical organization during race weekends. These contain race results, qualifying results, points standings and quotes from participants throughout the event's duration. Most of the tracks in the Warren Collection are those in the southeastern United States, including Lowe's Motor Speedway, near Charlotte, North Carolina.

The collection is arranged in 7 series: Photographs includes a limited number of photographs - 98 standard format and 5 oversize photographs, as well as 23 photographic slides; ARCA is primarily comprised of driver, speedway, and track memorabilia; NASCAR is the largest series and includes media kits, promotional materials, race memorabilia and statistics; other races documents numerous organizations, but is limited in size; and non-motorsports sports advertising; Digital Media contains CDs and other digital objects for several different tracks, including Darlington and Lowe's Motor Speedway and Reel-to-Reel Tapes contains four reel-to-reel tapes.

There are a few publications included in the collection, mostly annual NASCAR Preview and Press Guides, as well as race programs from individual speedways.
