One hundred years from now what will people think of Post-it notes, wind-up toys, or the technological marvel of our generation, the smartphone?

Future Harvard faculty, students, staff, and administrators will have the opportunity to examine these early 21st-century items. They are contained within a time capsule that was placed in the outside wall of the Tozzer Library at an Oct. 17 ceremony to mark the building’s renovation.

Tozzer, one of the world’s largest anthropology research libraries, is undergoing a complete renovation which will unite archaeologists in the Peabody Museum with anthropologists when both relocate to Tozzer upon its completion this spring. The goal is to strengthen the disciplines within the department by bringing them together and to make Tozzer a series of collaborative spaces in addition to a facility for book storage.
