 ########################################################### TODOS (next 29):
-TODO-28:	make books.html have page_title? and pass in a 'print these cols'... at least for poor ratings, etc. so we can hide dud columns, and show more useful ones
 TODO-27:	from missing, exclude any series where the only books we have are SOLD
 TODO-05:	should deleting really just ask if want to mark it as SOLD?  IN FACT, make delete button disabled until its sold... (and a tooltip to explain)
 TODO-09:	show books to buy view / printable
