The # signals that what follows it is some Scheme code (a Scheme expression).  
In this case #part-first-page happens to refer to the same thing as 
\part-first-page.  Generally it’s clearer to use the \ form in cases like this 
(and save # for inserting some Scheme code that doesn’t have a \ equivalent).
