Today's libraries are not just for books, computers and magazines – the Salem Church library now has its own geocache!

There are over 1000 caches waiting to be found within a 25 mile radius of the Fredericksburg area!

Earlier this month, after fifteen years of research, scientists reported that they had identified Ardi’s skeleton as the oldest hominid known to modern humans. Ardipithecus ramidus, as she is formally known, lived 4.4 million years ago in what is now Ethiopia. She’s remarkable not just for her age, but for what she tells us about human evolution.

Let’s talk about eBook readers. I’m sure you’ve seen one by now. Rectangular pieces of plastic capable of storing thousands of books to be read anytime, anywhere.
