Decimals were not invented or in any way involved with Dewey, he used a decimal system for catalogueing books but that has no more to do with decomals than, say the myname.myspace.com points do. Here is a list of decimal advocates from Wiki, google any of them for their history:

what are the virgos best days????

Generally, any day they can rearrange the cupboards, fold all the towels the way THEY want it done, line up all the medicine in the bathroom cabinet according to size, and categorize all their DVDs by Dewey decimal system without anyone telling them how obsessive/compulsive they are.

Does anyone remember the title of a movie about people using a library to survive the end of the world?

It does sound like The Day After Tomorrow but the reason i guessing its not that movie is because "and it was primarily to teach kids about the dewey decimal system"

In Day after Tomorrow, they are in a library and everything flooded and then turned to ice in the storm. They did use 1 book to solve a problem dealing with a person cut on a leg. Other than that they burned the books for heat. They ran into the library to get away from the wave of water flooding the city.

If its not The Day after Tomorrow do you remember any other details?

Here is the link to Day after Tomorrow to see if that is the movie, it provides more details of the movie.
