Three piles. 1) books I will take back to San Miguel de Allende. 2) books I will keep in storage. 3) books I will get rid of by selling or giving away. This is really hard work for me. I have a lot of books. A LOT of books. I want to read them all before deciding. It's also very entertaining, glancing through books I haven't opened in years, such as this copy of As I Lay Dying that I last read in high school.
