chants of the Roman Pontifical

Are the chants of the new edition of the Roman Pontifical available electronically anywhere, much like the chants from the Roman Missal. Having briefly seen the book, it appears to contain a wealth of English ceremonial chants. Is there a way to access these without purchasing the 150 dollar book?

If these are not currently available, is there anything the CMAA could influence to obtain them? or are they copyright protected somehow?
