I'm an Editor in book publishing. All opinions are my own.
As I was logging onto the website of my library system to manage my account, renew some books, and order new ones, I realized an important fact: browsing and requesting books from my library online gives me the same satisfaction and sense of anticipation as browsing and purchasing something from a website, except it's free!
This is extremely important in my life, as I'm one of those people who periodically needs something to look forward to as a little pick-me-up. Often that "something" must be purchased. It can be something small--a scented candle, perhaps, or a new pair of shoes. To get this same feeling for free, though, is amazing. Libraries, you are amazing.
