Fees are subject to change without notice.
Primary Publisher Annual Member Fee is based on the number of journals available online. Publishers must deposit metadata from all their online journals in the CrossRef system. Before retrieving DOIs for references in articles, Members must deposit the article metadata in the CrossRef system. In other words, in order to link from an article, the metadata for that article must be deposited in the CrossRef system so that others can link to the article. Organizations with both primary and secondary divisions must pay an annual member fee plus an annual administrative fee if DOIs are used in both primary and secondary content.
