Frat, by for DU student Scott M. Savoie , a controversial new book that explores the modern fraternity system, has been hit with a POD advisory warning.

The POD distinction makes it impossible for most bookstores to stock the book because of Parental Order and Delivery rules.

While most stores technically carry the book, it can only be purchased through special order, and cannot be carried on the shelves.

“This amounts to an X rating” says the publisher’s spokeswoman Katalin SzabCB3. “This makes it impossible for us to get distribution through the normal channels.”

While the publisher acknowledges the subject matter is not for children, though it insists the material is suitable for young adults.

One retailer said the decision was strictly a business one and not based on politics.
