From the earliest days of markup languages, reference tagging in scholarly publications has presented unique challenges. References to journals are relatively easy to tag, once a publisher has settled on a consistent structure. References to non-journal content such as books, conference proceedings, and “gray” literature, however, can present unexpected or awkward situations, and even journal references can occasionally prove idiosyncratic. We have a dedicated skilled team with a enriched experience for tagging the references/bibliography for all types of process like Journals, Conference, Books, Magazine, Standards. We are well versed with concept for tagging references in DTD like JATS, DTBook etc.
