Our tools and services allow people to find, link, cite, and assess your publications. This leads to greater discovery and tracking of published research outputs.
We have over 7000 members from 112 countries. Many types of organizations interact with Crossref and there is almost certainly an agreement that’s right for you. For publishers, in order to become a member, register content and deposit metadata you’ll need to meet one criterion:
You publish scholarly content that is available online and/or you represent organizations who publish.
Your content could include:
If you don’t meet the criteria to become a member but instead want to look up metadata or add it into your own software, check out our Metadata Delivery services.
Joining Crossref is a promise to look after your content. For our part, we promise to maintain and develop the community infrastructure for the long-term.
Membership therefore comes with a bit of work on your end. Crossref publishers make every effort to improve the quality and completeness of metadata. Once you’re in, we give you a prefix for your DOIs (Digital Object Identifiers), you create the suffixes and you begin to register content with us.
You do this by regularly depositing metadata that includes persistent identifiers and comprehensive information about the content. Your work to create and maintain the metadata is ongoing.
Before applying to join, please read a summary of your membership obligations.
