While I'm here and book posting, this one came from the Little Professor: Which authors dominate your shelves? (Domination = five or more books)
This is from memory, since most of my books are at school, but here's a guess: Louisa May Alcott, Madeleine L'Engle, Maud Hart Lovelace, L.M. Montgomery, J.K. Rowling, Valerie Tripp, Shakespeare, Ann M. Martin, Toni Morrison, Laura Ingalls Wilder, Irving Stone... ok, I'm not sure I can think of any from my shelves at school that I have in such volume, except L'Engle. (I do not count either General Convention or the Standing Committee on Liturgy and Music as an author.) These are all from home.
I'll keep thinking, but now it's time for shower and bed.
