Scholar is built on an open, editable bibliographic catalog: https://fatcat.wiki
Most of the records are automatically imported from our wonderful upstream sources, but any human can directly submit corrections and additions through the web interface or API. These submissions are then reviewed in the open before merging. The entire catalog is versioned and can be downloaded in bulk or synchronized using a "changelog" feed.
