Though it doesn't solve the current situation, a new feature may make the existence of IMSLP more palatable to music publishers and others with commercial interests. This is to include links to publishers and other vendors on the web site. No, I don't mean advertisements. I'll be more specific.
Presently each work has a main page, with basic information and download link. Behind this are tabs for 'discussion' and 'history'. I propose we insert a second page named 'links' or 'other editions' (does someone have a nicer name?). This page - also in wiki format - would be available for people - especially publishers, reprinters, vendors etc. to add links to their wares. These links would be directly applicable to the work displayed on the main page. This page could include links to newer editions, miniature scores, arrangements, DVD compendia, MIDI files, even recordings - public domain or otherwise.
One requirement for such links might be to allow a maximum of two lines of description per item. Another might be to require the link to point directly to the equivalent published work, not just to a web site main page (after all, we can all do a Google search if we want to!) All in all this would be very much like the 'External Links' category on Wikipedia pages, however we would keep it on its own page as described above.
Though I have described this feature as a vehicle for commercial participation, it would be useful for everyone. Most of us purchase and make use of originally published editions of scores and parts. This is not necessarily because this is all that's available. It is always more useful to have a nicely bound score than a stack of loose paper. In that regard, I would guess that the total cost of printing the score of a symphony on an ink jet printer would exceed that of purchasing a miniature score.
