Help w/NHD Projects!

Get help from a librarian with your National History Day project.
  • December 2017 & January 2018, by appointment only
  • Are you working on a project for National History Day?  Not sure how to pull it all together or maybe stuck on how to get started? Our librarians would love to help you. Schedule a one-on-one appointment with one of our professional librarians to get as much or as little help as you need with research and thesis ideas, as well as locating great resources that will wow your teachers. This year's theme is "Conflict and Compromise in History."
  • Appointments are available throughout December and January, including after school and Saturday times.
  • For students in grades 6 through 12 only.
  • We will begin taking requests for appointments here on Monday, November 27 at 10 am. Complete the online form, and you'll be contacted by a librarian. No email address? Call (303) 651-8477 to request an appointment.

The Friends of the Longmont Library generously support library programs and services.
