Trove, the National Library of Australia, provides a search engine and metadata for a wide range of textual, audio, and visual sources. Searching by the subjects “Corinth” and “Corinthe” pulls up numerous records for books, pictures, and articles. While most of the bibliography are common to other databases like Worldcat or Google Scholar, I did find useful the separate section on historical maps of the Corinthia (here and here) dating to the 17th-20th centuries.
