The bills would require the state to put out bids to create the open-source material for the top 50 college classes. It would also allow students to buy printed copies of those textbooks at a significantly reduced cost.
The bills' backer, Senate President Pro Tem Darrell Steinberg, says publishers currently charge "exorbitant" prices for the materials. He says the cheaper alternative would help offset soaring tuition and fees.
The American Publishers Association opposes the bills, saying publishers have already put many textbooks online at lower costs.
SB1052 passed 32-2, while a companion bill, SB1053, passed on a 33-2 vote Wednesday. Both bills now go to the Assembly.
