Sometimes I go to Wikipedia for fast musical knowledge like facts, Opus numbers, etc. but time and time again I find the resource is inconclusive at best. There are incosistencies within the structure that take you to foreign pages written by a different author with a completely different mechanism of organising the output of the works. Plus, Wikipedia is riddled with all kinds of commentary that borders on the subjective- but the authors are so good at doing it that you simply take it as knowledge if you read the article quickly and carelessly.
I’ve discovered a great resource for piano music on the Internet, and no this is not an official endorsement and I am not getting paid to advertise for these people! It is called http://www.pianopedia.com/ This resource provides just the skeletal, informational data of many pieces of the piano, plus it is accurate and consistent. There is absolutely no additional commentary whatsoever, and each catalog, or subdivision, is entirely thorough and consistent in its information. I highly recommend it for those looking to browse for new repertoire to learn and to put together a recital program, because the site also gives you the “average duration” of each movement- not just the work in its entirety- so it is more accurate.
