Since we started homeschooling we've used the library even more than your average bibliophiles. Our library has a 100 book limit on each card, and we have occasionally needed more than one card to leave the library with all our selections.
I try not to buy books so much any more. Not only could I not afford to buy all the books we want to read, but we have quite literally thousands of books already. Despite a large room filled with wall to wall book cases, and book cases in every bedroom and hallway, we just don't have room for anymore.
Sometimes I find myself renewing a book the maximum number of times and then checking it out again. When I do that enough I can convince myself that, yes, maybe we should buy this book. "The Best Old Movies for Families" is one of those books. It has not only lots of great suggestions for movies I had forgotten about, or didn't ever know about, it also has enough description that I can gage whether my extra sensitive kids would be able to deal with the movie.
Teach with Movies is a website that has more suggestions. (Although it looks like it's geared to high school kids. Your mileage may vary.)
Media gets a bad rap, but really it's they way the media is used that is the issue, not usually the media itself. There are some excellent resources out there to help parents find the good stuff.
I'd love to hear about any resources you know about.
