Josh, over at Parshablog, brings us this excerpt from Rabbi Falk's book Oz VeHadar Levushah:
Rabbi Falk advocates "doctoring" books that don't agree with what the Torah says. He specifically speaks to the issue of the age of the universe, but I would be willing to wager that he means this to apply to other areas where the encyclopedia disagrees with traditional Torah statements. As a result, Rabbi Falk has a lot of doctoring to do in his encyclopedia:
Just about everything about astronomy has to be "doctored," as no encyclopedia that I know of states that the geocentric model of the universe is the correct one, as the Rambam has it. Certainly no encyclopedia mentions (except, perhaps in the mythology section) that the stars are attached to a sphere which revolves around the earth each day.
Much of geology has to go out the door, because of the age of the universe problem. Likewise with archaeology -- you can't read that there are cities have been inhabited continuously since before the days of Noach.
A good deal of biology naturally has to be ripped out as well. Evolution, as you can imagine, is a big no-no. However, I'm fairly certain that most encyclopedias do not mention spontaneous generation (as in lice, or half-earthen rodents) as fact either.
Much of history has to go as well, since, in many places, the current historical understanding of events/places/dates may not match the traditional Jewish chronology. In addition, some historic events may involve details that we may not want children getting a hold of.
A fair portion of the section on genetics and its related entries have to be expunged as well. After all, genetics and mutations form a basis for the study of evolution.
Any of the sections dealing with biblical personages have to be cut out. Surely these are not written from a Jewish perspective and will contain information or allegations that are contrary to traditional Jewish thought. In fact, the whole section on Biblical books will have to be cut out (due to the Documentary Hypothesis and other similar theories), as will the entire section on Judaism - since it too, no doubt, contains misinformation about Judaism (for starters, that there are other branches of Judaism...)
Sections dealing with other religions, theology, mythology and religious personages have to be chopped too. Can't have mentions of other religions that aren't completely derogetory.
Any section dealing with popular culture (movies and their stars, radio programs, television programs, celebrities, etc.) also have to be removed.
This list is by no means complete. I'm sure that there are plenty of things that I missed in my list. So, after all this material is cut out of the encyclopedia, one has to wonder what is left?
