Regular visitors of MusicWeb International will have seen this – The Cello Concerto: An Overview and Timeline by Patrick C Waller. I for one am always happy to have such overviews and lists. Here's the link (http://www.musicweb-international.com/cello-concs/cello-concs.htm).
That's a pretty staggering piece of work, not just a list but a short paragraph on every composer with follow-up links (albeit non-comprehensive) to recordings, publishers and reviews whenever possible.
It is, as you say, a fine and valuable piece of work. However, what is signally lacking (as so often in such otherwise commendable compilations) is the all-important information, in each and every case, as to the existence and whereabouts of the full orchestral score (and/or parts) of a particular concerto, without which, of course, proper performance is impossible.
It's a great starting point though, surely, for those who do have the expertise to track down the scores?
Oh, I am not belittling the achievement, as I hope was clear from my comment. Merely highlighting what, in my experience, is a frequent and important omission from such online resources: the author has left out the hardest part of the research. And you, Mark, will know exactly what I mean!
Indeed I do. Eight years before the mast in my case, Gareth!
Quite so.
