I don't think there is an equivalent in, say, the humanities, or individual disciplines within, or at least one that would catalog the DOIs. (JSTOR and Philosopher's Index don't have DOIs.) But I could be wrong. I was thinking, instead, that the DOI could be matched against the particular journal publishers' databases online, e.g., journals.cambridge.org.Jon wrote:But what is the PubMed equivalent, then, that would allow you to look up the reference information (author, title, etc.) based on the doi and get it back in an intelligible form?
If it's worth pursuing, I can send you sample PDFs from Cambridge, Oxford, Springer, and Informaworld.
