Too Many Records , Too Little Time Member since Jan 2013 306 Points | Have I explained here how a lot of the inventory management and record company catelogs were created (I think) ?
I am pretty certain "Holerith" and other tabulating machinery cards were involved. There would be "static data" relating to the disc content - Cat/Matrix number, title, artist . publishing co and so on. So this data would be read in ( from a operator looking at each card for the disc ) , Orders would simply have a dynamic set of (one time use?) cards with Cat Number and whatever needed on them , run the two sets and create the shipping note/invoice etc and tabulate total sales for the day = create output card of sales for the day + yesterdays sales to date = end of day sales month to date (or re-run the daily sales orders / production information whatever, cross check production-sales = inventory in warehouse. (this could also be done manually) but all stratightforward for mechanical calculating devices that I am sure EMI and Decca would have had. However it is interesting that the likes of Brian Rust / Sandy Forbes never looked at this data source - maybe it had been destroyed and only worked off the books produced (ones sales catelogue would effectively be a Multigraph output from the data cars) , and Rust etc were only concerned with discs and recording dates/ persons rather than total monthly sales by disc. It would have been important to count discs sold - for the purchase tax returns and the royalty payments (though I suppose someone doing simple bar and gate totaling (or count the boxes of 20 discs at a time shipped out ?) could equally run the system
