In the past, I used to look through 30 or 40 volume encyclopedias to find detailed answers to many questions, from science to art to nature. Now instead of poring through dusty books we can simply hop on the internet and find a multitude of answers. The only real caution is to be sure that your information is coming from a reputable source. I also remember going into the school library to find Bible commentaries, set up much the same way as encyclopedias. What I wonder now is whether these Bible commentaries can be found on the internet, just like encyclopedias are available on-line.
