Dvorák cello conversion kit
It was common practice for 19th century composers to use the treble clef for cello passages in the high register, intending them to be played an octave lower. While these passages have been transcribed to tenor clef in Beethoven, for example, this false treble notation (dubbed "trouble clef" by a friend who is an amateur cellist) persists in much of Dvorák's chamber music. We realize that there is some reasonable doubt about the meaning of the notation in Dvorák, but the common performance practice is to play these sections down an octave. This kit allows you to replace the false treble clef with tenor clef, or true treble clef where necessary.

National Association of Composers/USA
NACUSA is a union representing nearly 200 composers, offering compositions for a dizzying combination of instruments. So if you are looking for a trio for piccolo, electric guitar and washboard, this might be a place to start your search. I visited some of the composer sites, and some are pretty good.
