That's true, but there was no book at the library that listed which articles in the newspaper we decided to read and which ones we decided to skip. The post office didn't make copies of all our letters and the phone company didn't record all our calls. When we used a map to find directions, none of this information used to be recorded. When we had our photographs developed, we could be quite sure the photo lab wasn't making copies of all of them.
Records of our financial transactions were much more limited because most of them were cash. Now we use payment cards for almost everything.
