I'm a horrifically slow reader, so I won't hit 100, but I thought it might be fun anyway to keep track of my reading this year.
Some of these books are ones I'm teaching this semester for a course on Romanticism in Spanish literature (but still a joy to read, of course, since I can choose what to teach), and will be labeled as such.
