Not sure what you mean by 'included with the minutes' as minutes usually are themselves a self contained document separate from other proceedings of a meeting.
The only (hard copy) meeting document which is normally issued as a matter of course is the agenda and presently with Zoom being forced upon us it is not really practical to provide hard copy of that. However the agenda should be downloadable from your councils website several days prior to the meeting at anytme not just the present. The same should be so regarding any ongoing operational records that are of public concern or interest including your councils expenditure, ongoing running cost, planning issues and so on. Everything should be completely transparent. The only area you are not entitled access to is the private section of a meeting as that is normally reserved for personal items or other confidential issues that have been brought to the councils attention.
If you feel there is some information that is of public interest/concern which is being intentionally withheld you can of course request that information under the Freedom of Information Act, but that is getting a bit heavy and of course is unlikely to be appreciated by your council. It would be much better that you first search your councils website (presuming they have one) and if you can't find what you are looking for just ask the Clerk where/how you can see it, you are perfectly entitled to do that.
NB not all information has to be revealed under the Freedom of Info. Act. If it is confidential or contains an individuals private details etc. or may infer a judgement by the council and so on but I would seriously reserve that route as a last resort and keep it amicable if possible.
