The Dewey Decimal Classification is terrible. It's an incredibly dated system with serious flaws like an pervasive European/Christian bias - for instance, notice that class 200 ("Religion") is almost entirely devoted to Christian topics, with a single subclass 290 for all "other religions" - and a lack of effective classifications for modern technical topics. It's also basically useless at classifying works of fiction, to the extent that most libraries don't even bother using it for that purpose. Standard practice is to group all fiction into a few broad categories (like "mystery" or "fantasy", as well as a catch-all for general fiction) and shelve them alphabetically by author. Needless to say, this isn't conducive to browsing.
