I first tried
   deb file:///home/richard/dvdmount pool main contrib
Then
   deb file:///home/richard/dvdmount pool/main/
   deb file:///home/richard/dvdmount pool/contrib/

Both gave " ... does not have a Release file" messages.
The later also said:

I suspect I'm running up against two things:
1. Documentation (esp man pages) authors assume *ALL* readers have
    the same background they do. I don't. {I was on the other side
    ~50 years ago as an Engineering Co-op student writing the
    inspection manual for a new oscilloscope ;}
2. Changes in what apt identifies acceptable repositories.

I intend to experiment with modifying files in /etc/apt/apt.conf.d 
rather than modifying sources.list. This will require I dedicate a 
separate machine to the experiment. I will also use that machine to 
compare stretch to earlier releases.

If you have multiple machines, then there's a method I haven't seen
mentioned, which might be worth a try. It doesn't require any unusual
configuration parameters.

Install apt-cacher-ng on one of the systems, then copy all the .debs
into /var/cache/apt-cacher-ng/_import and let it place them all into
a repository. You control the package by pointing your browser at
http://localhost:3142/acng-report.html on the caching machine, and
use the cache by inserting into /etc/apt/apt.conf a line like
Acquire::http::Proxy "http://192.168.1.NNN:3142/"
depending on your network configuration.

Cheers,
David.

For idiosyncratic reasons I do not have a network.
However, when I purchased the second machine, it was with the intention 
of occasionally erasing the disk for new experiments. IIRC a single 
machine can physically have both a server and a client. More reading to do.

You addresses a related issue, download bandwidth.
My current project is explicitly focused on using installation DVDs, or 
preferably their ISO images, as a 'repository'.

Why that is my goal is long and involved.
Part of my motivation is self-education.
What I want "should just work" <chuckle>
"Why doesn't it?" is my current assignment {essay}.

You would be better off with a bit of lateral thinking.

Your declared problem is to use the files on the ISO image of an
installer DVD as repository. So, you could create a package archive
from them as described at

https://wiki.debian.org/Installation+Archive+USBStick

and go from there.

But, you say, the ISO is not being directly accessed. Quite possibly.
However, the method advocated has the advantage of working and (up
'til now) nobody has come up with a working something to satisfy you.

Try [trusted=yes] and/or [allow-insecure=yes]  --- the brackets
are part of the syntax.

Indeed.

That command leaves users without root privileges out in the cold.
udevil is one remedy on the command line to stop them shivering.

Along the same lines - I imagine a modern DE can mount an ISO for a
user without the need for her to become root.

I'm going to get in trouble for this but if I could offer advice.
You seem more interested in the actual install process than getting it 
running and doing something with it.
Fair enough, it is like a hobby,
When came across this stuff I was the same, installed whatever 
distribution on awkward hardware just to see.
But I had no idea what I was doing.
There is so much to know and if you have a memory like a sieve like me 
it is really hard to grasp how it all works.
These days I accept the default installation and that which is needed to 
do bits of image manipulation and I really like having the email and 
webserver software and that's it.

Close ;}
Debian can do every real-world task I've tried.

My 'hobby' might be described as "Why does Debian do things the way
it does?"

On one installation the installer requested if I would like to use the 
CDROM as a repository and put this line in sources.list which I later 
commented out because I didn't want to have to keep searching for the 
CD.

Due to bandwidth constraints [originally on dial-up, now just a low data 
cap] all but one of my installs have been from purchased DVD sets. 
Although I tend to accept defaults, I habitually use the installer's 
"Expert" mode. The closest to "...if I would like to use the CDROM as a 
repository..." I've been asked was if I wished to scan additional CDs. I 
often did. After leaving dial-up I began installing new packages from 
the online repositories, although I continue to upgrade my system by 
doing a fresh install from DVD sets.
