A journal is rarely only its articles. The book your editors published, the proceedings of your conference, the thesis your university awarded, the dataset behind a paper, the review a referee wrote, the grant that paid for it.
Each of these can carry its own DOI, and each one is a place your work is found and counted. Until now most publishers could only register articles, because that is all their platform offered.
We now register every record type Crossref accepts: books, chapters, book series and sets, conference proceedings and papers, theses, reports, standards, databases, datasets, preprints, peer reviews, pending publications, figures and supplements, journal titles, and funding grants.
Each one is registered with the people credited by their ORCID, the funder named, and the links between the pieces kept - a chapter to its book, a review to the paper it reviews, a dataset to the article it belongs to.
