A good thread might be web sites.  I found one.

http://www.pianopedia.com

Just a database but could be useful for some.

Other links I recommend:

http://www.nosuch.com for keykit info

http://www.classicalarchives.com/ for midi files

http://www.pandora.com for a fabulous on-line music experience!

http://www.mutopiaproject.org/ Lots of music freely available
Others as I find them
