The garbage room in my condo holds more than trash bins. Next to the bin designated for paper a six-foot-tall bookcase sits flush to the wall. People put the books they no longer want on the bookshelf. Most books cycle through and find a home. Few books stay here forever with the possible exception of Bill Clinton’s memoir My Life. So last week I was astonished to find an old hardcover book stuffed inside a trash bin. It was unthinkable that anyone would throw away a book.
