I was just looking for some thoughts on the practice of pedaling outside of where the composer has specifically pointed out where to pedal. For example, in Chopin's 3rd etude, in e major, he has only marked for the pedal to be utilized in a few measures, but I think it is better to use it throughout. What I mean is, is it more the composer's intention for his piece to sound the nicest, or to be played exactly as it is written?
For fully detailed pedal markings, look at scores by Percy Grainger. He went to more trouble than any other I can think of.
For general guidance, see the surprisingly thick book, 'The Pianist's Guide to Pedaling' by Joseph Banowetz.
