Hidden enumeration

It might be too much to ask for a standardization of where enumeration and chronology are placed on a journal. So, I am content to hunt for it on the spine, the front cover, the back cover, the title page or within the publishing information. I have found a pattern of the news and sports magazines putting this information at the end of the editorial section on the last page and that is all right too. I am befuddled, though, at the publishers who cannot consistently put this information in one place. It might hold allure as a scavenger hunt for my assistants if it happened only occassionally, but....it has become a pattern for several journals. There is an entertainment magazine that I have given up predicting enumeration for. I only do cover chronology for that title anymore.
