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.

Here are some common questions (and answers) about content registration How do I register my content? You’ll need to send us your metadata via an XML deposit or using our web form. Note that you don’t send us the content itself – you create a metadata record that links persistently (via a persistent identifier) to the content on your site or hosting platform. Step-by-step instructions are available in the Content Registration guide.
Here are some common questions (and answers) about updating and maintaining your metadata records. My content has moved, how do I update my URLs? You can update your URLs by re-registering your content with the new URLs included, or send us a tab-separated list of DOIs and URLs and we’ll update them for you. If you are providing a tab-separate list, we can usually process your request within 24 hours.
I love reports but you never send me any - what’s up? I hate reports, can you stop emailing them to me? I need information about something that’s not covered by your reports, can you help me? What does this email mean? You sent me a DOI error report - what do I do with it? I keep getting DOI error reports for DOIs that I have not published, what do I do about this?
How much does Multiple Resolution cost? How do I update my Multiple Resolution URLs? I want my links to go to one place - how do I turn off multiple resolution? How does multiple resolution affect my resolution statistics? What if I want to do multiple resolution but sometimes want to direct people to a single URL? What if I want to use different URLs based on where the user is coming from - do you support country codes?
Scholarly and professional publishers are increasingly publishing book content online and depositing the metadata and identifiers with Crossref. Crossref has a critical mass of nearly 13 million book titles and chapters in its system of which 1.25 million are book titles. This means that there are nearly 1.25 million titles available for reference linking and other Crossref services like Crossmark and Similarity Check. However, reference linking from and between books is more limited than with journals because many books and book chapters are in PDF so the references are extracted, deposited with Crossref and linked.
What is Co-access? What problem does Co-access solve? Who is Co-access for and how does it work? How much does Co-access cost? How do I participate in Co-access? What is the difference between Multiple Resolution and Co-access? Can Co-access be used for journal content DOIs too? Doesn’t Co-access violate the “uniqueness” rule? What about citation splitting? How does Co-access affect resolution reports? How are Co-access relationships represented in Crossref metadata?
What are Participation Reports? Why do I need to look at this report? Do I need to log in? Are Participation Reports only for Crossref members? Does it cost anything? How do I look my organization up? Is it by name or by prefix. Can I look up any publisher/member? Will anyone be able to see my data? What content types are covered by the report? What do the percentages next to the boxes mean?
