Parents need to know that they'll have to fork over $70 a year to access all of this site's content. It may be worth it as you won't have to worry about your kids coming across any inaccurate and inappropriately presented material. Yes, your kids will be able to read about penises, but the entries will be scientific and straightforward -- and they won't have any explicit images to go alongside them. There are ads, but they're minimal and all linked to things that will improve your mind, and a link to the Britannica store.
Educational value:The idea behind an encyclopedia is to learn things!
Violence:Entries about violent topics (such as war) aren't glorified and are similar to what you'd find in a school textbook.
Sex:Entries about sexual topics are straightforward and educational. The illustrations that accompany them aren't explicit. For example, for vagina, it says "canal in female mammals that receives the male reproductive cells, or sperm, and is part of the birth canal during the birth process" and a drawn diagram calls out the different parts.
Consumerism:If you want access to entire articles and parts of the site, you have to pay $70 a year. There's a link to the Britannica store and ads to magazine and educational items.
What can I say, it's Encyclopedia Britannica.
But for all that is good and holy, never EVER confuse this with "Encyclopedia Dramatica." ever. Words can never describe... the horrors on encyclopedia dramatica.
