Metadata Retrieval

Interfaces for Machines There are APIs for machines (to look up metadata records or DOIs in volume), including: REST API, XML API, OAI-PMH, and OpenURL. Interfaces for People To retrieve metadata from Crossref, you do not need to be a member. We have various options for retrieving metadata - some are more suitable for human use, and some for machine use.
