These files were selected from a much larger series inherited or created by the secretariat of Aberconwy Borough Council that were deposited with Conwy County Borough Council's Modern Records Service at the local government re-organisation of 1996.
The series was appraised in its entirety and either selected for permanent preservation on the grounds of historical importance, recommended for disposal or offered back to Administrative & Democratic Services (which succeeded the County Secretary's Department) for ongoing administrative purposes.
It includes a small proportion of records inherited from the former UDCs that had been abolished in the earlier county re-organisation of 1974, as well as records created by or for Gwynedd County Council.
The series has been arranged loosely in alphabetical order of subject with a miscellaneous section at the end. Original reference numbers have been quoted wherever they existed.
