There are so many things to get rid of. Clothing that no longer works (for reasons untold), books, and other “stuff”.
But how?
Our concerns complicate our efforts by keeping us from simply putting everything in the trash to end up in a landfill somewhere. We want to be environmentally responsible and, if possible, help a charitable cause or two. Books pose the greatest challenge because we simply cannot just throw out books (for so many reasons).
So we find a few outlets. The thrift shop, a local collection truck that collects for several different charities, the book depository at the local library, a local bookstore, and our local recycling bin (at least it's environmentally appropriate). 
It takes effort, but it’s worth it.
