EFF has released "In Passing A.B. 2192, California Leads the Country in Open Access."
Here's an excerpt:
Under A.B. 2192—which passed both houses unanimously—all peer-reviewed, scientific research funded by the state of California would be made available to the public no later than one year after publication. There’s a similar law on the books in California right now, but it only applies to research funded by the Department of Public Health, and it’s set to expire in 2020. A.B. 2192 would extend it indefinitely and expand it to cover research funded by any state agency.
