con: Out of seven copies of this book in two Harvard libraries, only one is the right edition for my purposes (two weren't) and remains unmarked by generations of Harvard undergraduates underlining passages as they study (four copies were scribbled). That's really dreadful.

pro: I do love the smell of Widener's stacks. There's a musty vanilla-sweet smell to old books en masse that I adore. What is that? It's the smell of my parents' attic and of well-loved libraries. Now someone will tell me it's the smell acid makes as it slowly eats away at their pages and I'll be sad. But I do love that smell.
