This deliverable summarises the work done to compile a comprehensive overview of the landscape of literary corpora and sources currently available. It describes the methodological approach of the work group and analyses the various challenges encountered in the effort to collect information about these resources and consolidate them into a structured form. Based on an initial inventory of 86 corpora or corpus sets, the report exemplifies their wide variety with respect to structure, context and purpose, and consequently the differing modes of provisioning. It also proposes a technological path towards making this information searchable via a central discovery catalogue by discussing principal design decisions regarding the data model and the technology stack needed for such a task.
