I've been working on Scheme lately as well. I found the "Hello Scheme" section in the Guile 2.0 manual [1] to be a better introduction than the R5RS [2], though you need to be careful as we're still using Guile 1.8 and there are enough differences in 2.0 that it breaks Gnucash (but the manual was heavily rewritten between 1.8 and 2.0 and the latter is much better). Notice that the search "MIT Scheme Reference" produces manuals for Scheme 7, which Guile (even 2.0) does not support.
