ROAD is a new unified ISSN lookup tool, apparently from UNESCO, drawing records from a handful of big databases. What makes it notable is that search results only show records of open access titles. ROAD looks like it might be useful for finding out what’s currently listed where, e.g.: what open access title is in Scopus but is not yet in the DOAJ. ROAD also gives ISSN records that are otherwise held behind paywalls, in databases such as ISSN Register.

Drilling down through the sidebar filters shows ROAD listing only 338 titles in the Arts and Humanities + published in English, despite its accessing the DOAJ and many other databases. Odd.
