Summary
- An unpublished Dr. Seuss manuscript titled "Sing the 50 United States" was found.
- The manuscript was discovered in the author's archives at UC San Diego.
- The book features the Cat in the Hat trying to remember all 50 US states.

An unpublished Dr. Seuss manuscript, "Sing the 50 United States," was recently discovered in the author's archives at UC San Diego. The manuscript, found in May 2025 during a search for marketing materials, contains the Cat in the Hat struggling to remember all 50 states.
This discovery is considered 'kismet' by publishers, as it was found just a year before the United States' 250th anniversary. The completed manuscript, complete with sketches and a storyboard, required minimal editing, allowing for an expedited publication timeline.
The book aligns with Dr. Seuss's broader goal of supporting children's learning, focusing on U.S. geography. The accompanying song further highlights Geisel's intention for the work to be musical. His meticulous attention to detail, evident in his drafts, influenced the book's color choices and content.
The reasons for the manuscript remaining unpublished for decades remain unclear, though his known perfectionism is a possible factor. The discovery and publication of "Sing the 50 United States" occur amidst ongoing discussions about Dr. Seuss's complex legacy and the estate's decision to cease publishing certain books due to racist imagery.
