Donna Coletti is the head librarian at the
Harvard-Smithsonian Center for Astrophysics's Wolbach Library.
Coletti's everyday job consists of a mix and match of various tasks, which consist of overseeing all of the regular
library functions:
searching computer databases
ordering books
coordinating interlibrary loans
answering reference questions
The interesting thing about the Wolbach library and the woman who runs it is that the library serves over 600 people in Cambridge, Massachusetts, and is considered to be one of the world's preeminent astronomy libraries.
