The CWKB knowledge base assembles data about Classical works (1,550 authors and 5,200 texts, with variants forms in the main modern languages of Classical studies and common abbreviations). The knowledge base also contains the linking heuristics to the passage level for 6,732 manifestations of Classical works. CWKB does not aim at creating a new canon of Classical literature, but provides a concordance to existing canons and workID registries.
