As Textbooks Go 'Custom,' Students Pay

"College students, already struggling with soaring tuition bills
and expenses, are encountering yet another financial hit:
Publishers and schools are working together to produce "custom"
textbooks that can limit students' use of the money-saving trade
in used books. And in a controversial twist, some academic
departments are sharing in the profits from these texts."

I find this hard to believe. Lees than 50% of students, from experience, buy books anymore. Seems like great foddor for textbook 'torrent' advocates!
