While searching for something else, I happened upon the Alabama Archives Record Disposition Authorities for Local and State Government agencies. It addresses current records created by these agencies as well as the older records.
According to the website:
The State and Local Government Records Commissions review and approve the RDAs at their quarterly meetings. Once the Commissions approve an RDA, the agency or official creating those records is authorized to implement records disposition. Disposition may involve destruction of records that have met their legal, fiscal, and administrative needs or preservation of records identified in the RDA as permanent.
I have not read all of this, but one thing I found of interest was the following:
As part of its record-keeping responsibilities, the probate office must maintain copies of each daily or weekly newspaper published in the county. The newspapers document the probate office’s mandated responsibility to publish various notices to the public created in conjunction with its other duties.
