Dear Parent, Thank you for your question! I have never found a good catholic Encyclopedia set for Catholic children. However, the Childcraft Encyclopedia set is relatively safe. You can buy them used online through Alibris. Granted the set is old, but it is safe for your children. A good way to check your encyclopedias for conflicts of our Faith, is to look up the topic of birth control and abortion. Encyclopedia Britannica is a good set to use. However, unless there is a Junior edition, your 1st and 3rd graders will probably have difficulty using them. Encyclopedia Britannica would probably be more useful for middle and high school levels. God bless you and your family! Laura Nicholson |
