The LoveToKnow Free Online Encyclopedia is based on what many consider to be the best encyclopedia ever written: the eleventh edition of the Encyclopedia Britannica, first published in 1911. At a time when many encyclopedias have capsulated and condensed important knowledge, the 11th edition is generally much more in-depth and thorough on it's topics. It is not uncommon for our entries to be 5 to 10 times the length of other encyclopedias. As a research tool, this 11th edition is unparalleled - even today. LoveToKnow is in the process of updating and editing thousands of the entries, preserving the treasured entries that make it so unique, and adding entries on new relevant topics. We hope that you enjoy and learn from the LoveToKnow Free Online Encyclopedia and that it becomes one of your favorite places for reference information.
