Lending libraries (as they were first called) were a source of controversy when they were introduced in the 19th century. Publishers were concerned that they wouldn't be able to make any money if books were simply loaned out for free. Fast forward more than 150 years and it's clear that the entertainment industry is still making money despite the availability of free books, movies, music and even video games. However, many people still don't take full advantage of their neighborhood library.
You may have to wait a little while for a new release but, otherwise, you can access an evening of fun for your kids or yourself without spending a cent. Just think about the savings opportunity -- if you were to buy a novel for $20 or $25, you'd be lucky to get a $5 return even if you sold it to a discount bookseller. But it's on loan at your local library for free.
Technology can also be a lifesaver when it comes to your monthly expenses.
