Reducing Book Volume

Sorting through the books is hard because there are so many of them and holding each one in my hands brings to mind an unfinished project or a pleasant memory.  I need to find a way to decide what to discard without summoning those memories and feelings.  Maybe I can do this by taking an inventory, and then deciding what goes based only on the list.  The bankers boxes contain a total of 120 books.  Some I think I can let go right away, especially ones I’ve read that could easily be replaced.  Some I wanted to read when I bought them but never did – so not a great loss if I never read them.  Others I definitely do want to read, but can chuck them after I do.  Some reference books, and personal history type things I want to keep.  I should take the inventory away from here, to a diner and over lunch choose what to keep or toss.  Maybe put them into categories and only keep a certain number within each category.
