The stimulus for this problem is that Dorset Library Service was down completely yesterday, and the staff had to write down on sheets all the information about taking out and returns.
The proposal is to have a Raspberry Pi on standby to input the information, that can be later fed to Dorset Library Service to update their records.
This is possibly a project for high school students.
Our library cards identify us by a bar code, and our books have both a bar code and an RFID tag.
A means of communicating the results back to Dorset Library Service must be devised.
The Raspberry Pi is programmed in Python, which has a good facility for handling lists.
I have found a few links in the link below to how to read bar codes with a webcam, as the bar code scanner that I have doesn't seem to work. [ Looks like a faulty cable]

Using Memory card 1 (16GB) I am going to try some. This has Raspbian Buster on it.
I can either just scan in sequence all the codes, or I need a screen to show which type of data is being scanned.
