Bookplates. The link was stolen from Neil Gaiman and is mostly for my reference (I tend to forget about this sort of thing), and the bookplates are for kids, in theory, but there's several that can be used by adults without shame. ;) Now if I didn't have hundreds and hundreds of books (which would mean a lot of ink and printer paper, and would also mean that my father would kill me), and I wasn't so reluctant to lend them out (which pretty much eliminates any need for bookplates)... heh. Maybe I'll add bookplates to my favourite books when I tidy and catalogue my books. Which I'll probably do alle calende greche, like we say in Italy... heheh. (The Greek Calends are a good date to postpone stuff to. ;)
