I've just paid out $22 for a year's access to IMSLP.org - a free online source of the sheet music. I've just looked at the original edition of Playford's Airs, Debussy's own manuscript of his Mallarmé poems, and a 17th century harpsichord manual. Included in the price is a sub to the Naxos Music Library - 125,000 CDs available for streaming, from many of the big labels. I've just found the CDs I was part of recording back in 1993, as well as the Gimell back catalogue (a choral singing nerd's wet dream). All of this is legal. Many of you will already have access to the Naxos Library via your local library. Truly the internet is a wonderful thing.
