They seem to have grown legs and walked out. Or somebody decided to keep them as a new pet. Or a way to keep their coffee table level. Or to learn how to walk properly.
Either way, we don't have any on the shelf. Actually, most libraries around us don't. They seem to be the most popular book that people either like to keep or steal.
Luckily for us, we do have access to an awesome database. You might have heard of it. It's called the Learning Express Library. It's not just for GED, either.
It has SAT, ACT and a few other practice tests. It has computer tests, career tests, tests to help you remember your English lit and your history. And a bunch of other tests.
Not just tests, either. Just e-books and courses. And it's free as long as your library subscribes to it.
Thankfully for all of our GED-seekers, my library does.
ETA: We had a 2005 GED book returned the other day! No idea where it came from, but it was in such bad shape that I pulled it.
