Solutions to Pare Down Your Book Colletion
Set a read to purchase ratio. If you read 2 books a month, commit to buying no more than 2 books per month–just set limits.
Pass books along. Do you have a friend or colleague who might be interested in reading the book you just finished? Give them yours rather than allowing the book to sit on the shelf, take up space, and collect dust.
Donate. There are many organizations who would love to take books off your hands. Donate them to the charity of your choice. Try Open-Books.org in Chicago.
Swap. Go to Paperbackswap.com to swap online, or gather a group yourself and meet to swap.
Make use of the library. Not only for books, but movies, games etc. the library is a terrific source for clutter free learning and entertainment.
