The project consisted of four principal activities:

• Acquisition of digital images of Chopin’s first editions
• Comparative textual analysis of multiple first editions
• Adaptation and expansion of information derived from the Annotated Catalogue of Chopin’s First Editions 
• Development and refinement of the technical means to display these images and related text.

These activities were conducted by the Project Director and three Research Fellows at Royal Holloway, University of London, and by the technical team at the Centre for Computing in the Humanities (CCH).

An extensive revision process was conducted in 2014–15. The CFEO site was aligned with those for the Online Chopin Variorum Edition (OCVE) and the Annotated Catalogue Online (ACO), all three of which form the Chopin Online resource. This work was carried out by three colleagues at the University of Cambridge (the current host institution) and by technical collaborators at CCH’s successor, the Department of Digital Humanities at King’s College London (DDH).
