IMSLP stands for International Music Score Library Project. The logo is a capital letter A, taken from the very first press-printed book of polyphonic music, the Harmonice Musices Odhecaton, published in 1501. Its printer, Ottaviano Petrucci, is this library’s namesake. IMSLP is associated with the following Amazon sites: Amazon.com, Amazon.ca, Amazon.co.jp, Amazon.co.uk, Amazon.de and Amazon.fr.
