If the council resolves to pay the subscription fee, the council should benefit from access to the resources at the SLCC site.
If you have Cllrs that wish to learn more and be better informed, they should ask to have access to NALC and county ALC login and password AND the SLCC login and password.
It is divisive and often contentious when Cllrs seek access to these resources with clerks and ALC /SLCC supporting the notion that only clerks should have access.
This is patently absurd if (and I'll accept it is a big if) there are Cllrs that want to read up independently. This is often overtly prevented by a clerk since "knowledge is power" - my first tussle in this game was from a clerk with 20 years service to the PC telling me he'd tell me whatever I needed to know...
That didn't end well for him, 6 months after I joined that PC he threatened an Ind Trib, I countered with the proposition of a fraud investigation and he did a moonlight flit after arranging for the forensic wipe of the PC IT system.
Councils should adopt the approach - no access (to SLCC / ALC) resources - no subscription fee from public money. That would put a rocket up NA:C and SLCC who seem to have forgotten who puts the bread on their table
