crossref-works.json.xz contains Crossref metadata for 87,542,370 DOIs retrieved by querying works from the Crossref API.

Queries began on 2017-03-21 and completed on 2017-04-02. The process died or stalled several times, but was restarted using the API's cursor. Accordingly, the works should represent the Crossref database as of 2017-03-21.

crossref-works.json.xz is an xz-compressed file of exported works from MongoDB. It was created using mongoexport and can be imported into MongoDB using mongoimport. The file as a whole is not actually valid JSON. However, each line of the file is valid JSON and encodes a single work retrieved from the Crossref API. Accordingly, you can read this file without mongoimport by splitting at newlines and parsing each line as JSON.
