CrossRef linking improvement

CrossRef has implemented a fix that improves the results of eXtyles CrossRef linking of non-journal references. Previously CrossRef linking would sometimes return the DOI of a journal article that was later published as a book chapter, when the citation in the document is to the book chapter. This linking error would occur when only the journal article, and not the book chapter, had been deposited at CrossRef. It is now much less likely that eXtyles will insert a DOI link to a journal article for a non-journal reference that is substantially the same publication.
