This may seem like a simple question, but I have found a case example that is really difficult for me. It is an archival piece from around 1900, when such information was kept by register books or file cards.
Usually customer lists from sales departments or stores are an information tool for marketing and current accounting. The example in the appendix may have had a more special purpose:
Only two categories are displayed: one number (probably the customer number) and the name of each customer. I only found this one piece of paper. The headline shows that it was the first page of a longer list. The paper cut is located on the right hand, i.e there can’t have been further columns and categories on a conceivable adjacent page. So, this listing structure seems to be complete.
What was the purpose of a customer list, if neither the numbers nor the customer names were listed consecutively numerically or alphabetically? And why do some numbers appear twice or three times with different names, but often with the same city?
Apparently this was a list for a specific purpose. How was it worked out? What was the information base?
I have only a vague idea what it might have been. The flow logic of the lines could be chronological, perhaps from the order book of the previous year. Thus, it could have served to compile statistics on the number of active customers. However, I have doubts as to whether this was the usual method for producing such statistics. And if so, the list must have been of limited value as an only intermediate document for the final statistical result. Why did just this composition survive?
Does anyone have any alternative ideas on the case? I would be happy about any ideas, including vague, tentative or hypothetical ones.
