??Why do publishers join CrossRef?

To get persistent identifiers for their content

To drive more traffic to their content

To turn references into hyperlinks

To pull in cited-by links (who cites this?) to get more traffic

Participate in other collaborative services (CrossCheck, CrossMark, FundRef)
