It’s National Library Week!

Celebrate spring in the library with exhibits, activities, and experiences that explore the role herbs, plants, and flowers have played in the history of science and medicine.

Join our curators and librarians for a fun after-hours event in the Othmer Library’s reading room where you’ll have the opportunity to

  • see unexpected treasures not usually on display
  • get a temporary tattoo
  • make a craft to take home
  • enjoy a taste of spring with a special botanical-themed cake and other light refreshments
  • support the library by adopting collection items
  • and much more!

Admission is free, and registration is required.
