I was interested in knowing if a membership at the local library would be worthwhile, or rather if I'm ordering too many books that I could just borrow. So I compared my To-Be-Read/To-Be-Ordered list (collected with amParser) with the library's inventory.
Results: Of 73 TBR books (disregarding reference books) the library has 16, 3 of which are not in my preferred language, but only available as German translations. Better than imagined. Time to get a library card.
