"The Marshall Public Library doesn't believe in censorship, but we do want to protect our children, and this is something that they need to be protected from."

That's what one local library is saying after we informed them that a series of children's books they're carrying has the number for a sex line in the back.

If you want to join the Magic Attic Doll Club, don't dial the number in the back of the Magic Attic book series, because you'll be invited to join a club of a different sort.

A Florida woman first found out the hard way that dialing the number on the postcard found in some of these books gets you an ad that says this:

"Jump in to fun, exciting live talk talk now! Call 1-800..."

We then checked to see if the number listed in some Magic Attic books in the Marshall Library led to anything out of the ordinary, and it did.

"I'm totally astounded!" said Marshall Public Library Associate Director Kathy Watson. "It's very irresponsible to think that you sell your phone number, children are going to be calling, and then you don't care where you sell it, and you don't let people know what you've done either."

The books will stay on the shelves here in Pocatello, but not the postcards.

"They're maybe not the greatest read that you've ever had, but there will be kids, especially girls, who will want to try them sometime, but Kathryn's going through and tearing out all the pages with the phone numbers on them, so that's not going to be an issue," said Watson.

Librarians say parents should be the first line of defense when it comes to what information their children absorb.

"Parents should know what their children are reading," said Youth Services Supervisor Kathryn Poulter. "They should know who their children are calling."

And they've already called around to other libraries in Pocatello to warn them of the situation.

"If this was an actual postcard, that went to a number connected to the Magic Attic Club, that would be another thing because we want people to have the freedom to do whatever they like to. But this is misleading," said Poulter.

The books are no longer in print and the company is out of business.

The Associated Press reports that before that company folded, it was actually sold to entertainer Marie Osmond, and that a spokeswoman for her has said she wasn't responsible for the mix-up, because the books were discontinued.
