For my PhD thesis I'm using a BibTex database that I have used and extended over the years. However, over time I 'abused' it by deleting fields instead of creating copies and keep the main database with original entries.
I'm using JabRef but as far as I know this does not have an option or plug-in to mass "search and merge" my entries with 'correct' entries from other sources, whilst keeping keys intact.
Does anyone know if such a tool or service exists?
(since I'm in the field of computer science, a DBLP-specific service would already help me out big time)
