Thanks to the digital revolution also a traditional discipline like philology has been enjoying a renaissance within academia and beyond. Decades of work have been producing important results that are developing new research questions and educational resources. This volume describes the state of the art of digital philology with a focus on ancient Greek and Latin, the Classical languages of Western culture. Contributions address problems like accessibility of information about Greek and Latin sources, data entry, collection and analysis of Classical texts. The book describes the fundamental role of libraries in building digital catalogs and developing machine-readable citation systems of Greek and Latin works. A section is devoted to methods and standards for producing digital critical editions of Classical texts and critical annotations about them. The final part is about morpho-syntactic annotation and lexical resources of Greek and Latin with a discussion of topics that pertain to philology and linguistics. The aim of the volume is to describe an emergent field for a new generation of scholars and students, explaining what is reachable and analyzable that was not before in terms of technology and accessibility.
