This is the Cycle of True Marketing, which I discuss at length in my book, The Accidental Library Marketer. Many people who have not studied marketing make the mistake of doing just a few of these steps, usually from the middle of this figure. But true marketing, which is much more effective than bits of hit-or-miss, is a process that starts with market research and continues in a never-ending cycle. Following this process in full will make your efforts much, much more effective.
