Preserving Harvard's Data and Research in Astronomy

PHaEDRA is an initiative by the Wolbach Library, in collaboration with many partners, to catalog, digitize, transcribe, and enrich the metadata of over 2500 logbooks and notebooks produced by Harvard's Women Computers and other early astronomers. Our goal is to ensure that this remarkable set of items, created by a remarkable group of people, is as accessible and useful as possible.

PHaEDRA Full-Text

We are working with the Smithsonian Transcription Center’s Digital Volunteers program to crowdsource transcriptions of the PHaEDRA notebooks. Helping us transcribe the notebooks makes them full-text searchable on the NASA Astrophysics Data System.

Star Notes

We are using the Zooniverse to link the PHaEDRA notebooks to their source material: over 500,000 astronomical glass plate photographs. Making these connections will create a bridge between the modern scientific literature and 100 years of astronomical observations.

Project Partners

Project PHaEDRA has been made possible through a cross-institutional collaboration led by the Wolbach Library. Our digitization workflow relies on our astounding project partners at the Astrophysics Data SystemHarvard Library Imaging Services, and the Weissman Preservation Center. PHaEDRA also wouldn't be possible digital volunteers at the Smithsonian Transcription Center and on the Zooniverse. Thank you!
