Project: Haystacks

Where can I find Haystacks?

What does Haystacks do?

Haystacks is a tool for visualizing data about the Harvard Library collection.

Why does Haystacks exist?

Created with the generous support of the Harvard Library Lab, allows librarians, faculty, students, and others to experience the vast collection of the Harvard Library in a new way. It allows users to visualize changes in both our collecting practices and usage patterns over time.
