PHaEDRA is an initiative by the Harvard Plates Stacks, in collaboration with many partners, to catalog, digitize, transcribe, and enrich the metadata of over 2500 logbooks and notebooks produced by [Women Astronomical Computers](/glass-plates/women-at-the-harvard-college-observatory) and other early astronomers at the Harvard College Observatory. 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](https://transcription.si.edu/browse?filter=owner:11)’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](https://ui.adsabs.harvard.edu/search/q=bibstem:%22phae.proj%22&sort=date%20desc,%20bibcode%20desc).

 **[Start transcribing](https://transcription.si.edu/browse?filter=owner:11) notebooks!**



 

##  Star Notes 

 We are now using the Zooniverse to find astronomical sketches, graphs, and other non-textual items. Phase 1 (identifying plate numbers) of our project on the Zooniverse concluded in August 2022, and will be used to build a bridge to the original source material: [over 500,000 glass plates](/glass-plates)!

##  Project Partners 

Project PHaEDRA has been made possible through a cross-institutional collaboration led by the Harvard Plate Stacks. Our [digitization workflow](/digitization-workflow "Digitization Process") relies on our astounding project partners at the [Astrophysics Data System](https://ui.adsabs.harvard.edu/), [Harvard Library Imaging Services](https://imaging.library.harvard.edu/), and the [Weissman Preservation Center](https://preservation.library.harvard.edu/weissman-preservation-center). PHaEDRA also wouldn't be possible digital volunteers at the [Smithsonian Transcription Center](https://transcription.si.edu/browse?filter=owner:11) and on the [Zooniverse](https://www.zooniverse.org/projects/projectphaedra/star-notes). Thank you!
