There's a special issue of Digital Humanities Quarterly on the theme Transforming Classical Studies Through Cyberinfrastructure in memory of Ross Scaife, the founder of the Stoa Consortium for Electronic Publication in the Humanities, with lots of fascinating stuff, but the article that caught my eye is by Neel Smith on citation in the classics. I must admit that all my work and thinking about citation was during my medical librarian days.
Smith draws on the Functional Requirements for Bibliographic Records (FRBR) as a way of understanding the hierarchy of texts, and has developed the Canonical Text Services, a system for identifying and retrieving texts by canonical reference.
