If you publish scholarly content online or represent organizations who publish, you are eligible to become a member. You also must be able to commit to our member obligations.
We don’t supply DOIs ad-hoc. If the publisher of your paper is a member, they’ll register your article on your behalf.
Your deposit fees will be invoiced quarterly. Invoices can be paid through our payment portal. In addition to credit card payments we also accept wires, checks and paypal. Our Paypal recipient email address is ‘paypal@crossref.org’. Questions about logging in or billing in general can be emailed to our finance team.
To look up a single DOI use our Metadata Search interface. If you want to look up metadata records or DOIs in volume, read more about Metadata Delivery.
If you’ve acquired a title from another member, you need to let us know about the transfer and provide confirmation from the disposing publisher. We’ll accept transfers posted to the Enhanced Transfer Alerting Service (ETAS). If you don’t participate in Transfer, your confirmation may be a forwarded email from the disposing publisher to the acquiring publisher acknowledging the transfer. See our title and record ownership transfer policies for more details.
While we aren’t able to correct the metadata provided by our members, report any metadata issues to our support staff and we’ll contact the responsible member and ask them to make corrections.
Please contact our member services team with any changes to your contact information.
