Arkansas Board of Corrections could not overturn the existing policy of accepting books from approved distributors, because it had been enacted by the Arkansas state legislature. Therefore, the state legislature had to approve any changes. No date has been set for the legislature to consider the ban, which would require 30 days for public comment before a vote. Meanwhile, the current policy, that “Inmates may receive publications from recognized commercial, religious, or charitable outlets”, remains in place.

tl;dr - Old policy still in place until they decide how best to fuck everyone.

according to this: they are not allowed to receive books and other media directly, due to contraband concerns.

Donations of books by nonprofit groups or local libraries to prison libraries will still be allowed under the new policy, according to Department of Corrections spokesperson Rand Champion. The new policy only restricts how books are brought into the prisons, without banning physical media outright.
