I run a small library database for my company, most of which is based in England. Every month, a cron job sends a listing of newly added books, based on the record-creation date, to the library administrator, who then forwards it to everyone.
Yesterday, I got e-mail from the library admin, saying, "There was a problem with the book list—there were books on it that aren't new, but had just been edited in the past month. Several people complained, 'Wait, don't we already have that in the library?'"
So I run tests. I look over the code with a fine-tooth comb. As far as I can tell, there's absolutely no way this can be happening as described. I e-mail back, saying "Which books turn up as new that were already in? What sort of editing did the keyboarder to do these records?"
This morning I get an e-mail, "Well, the keyer didn't actually edit the entries—she just deleted them and then added them again with the changes made."
