Volunteers needed to preserve astronomical history and promote discovery

Before iPhones and laptops there were human computers, some of whom worked at the Harvard College Observatory. Women like Henrietta Swan Leavitt, Williamina Fleming, and Annie Jump Cannon made some of the most important discoveries in astronomy in the early 20th century. Their work was even featured in the TV series Cosmos, hosted by Neil deGrasse Tyson. Now, Harvard is seeking your help to transcribe the logbooks that record the century-long observations behind (and beyond) their discoveries.
