📖 About Crook County Public Library
The Crook County Public Library is the main branch of the Crook County Public Library System, headquartered at 414 East Main Street in Sundance — the county seat of Crook County, Wyoming, nestled in the Black Hills just 27 miles from Devils Tower National Monument. The library's founding board first met in 1938, guided by a mission to help residents cherish local history and expand their horizons through free access to information. Today the system operates three public locations (Sundance, Moorcroft and Hulett) and participates in Wyoming's WYLD network, giving cardholders statewide digital access through GoWYLD. A standout offering is the Library of Things, which includes Wyoming State Parks day-use kits — borrowing a kit grants free admission to any Wyoming state park or historic site for everyone in one vehicle for up to 14 days.

❓ Frequently Asked Questions
What is in the Crook County Library's Library of Things?

A standout item is the Wyoming State Parks kit: borrow a kit to get free day-use admission to any Wyoming state park or historic site for everyone in one vehicle, for up to 14 days.

Why is the Crook County Library closed on Mondays and weekends?
The Sundance main branch is open Tuesday through Friday, 8 a.m. to 5 p.m. (as of August 2026). Crook County is a rural county with a smaller tax base, so hours are set to serve the most patrons efficiently within the library's budget. The Moorcroft and Hulett branches are open Monday through Thursday — call ahead if you need a specific branch.
Does the Crook County Library serve the whole county or just Sundance?
The Crook County Public Library System serves all of Crook County through three branches: the main branch in Sundance, a branch in Moorcroft (open Monday–Thursday) and a branch in Hulett (open Monday–Thursday). Your Crook County card works at all three locations and also gives you access to Wyoming's statewide WYLD digital catalog.
