In the beginning, we didn't think about preserving digital assets, but only about creating them. In fact, it probably took a few failed projects for us to think seriously about methodologies around managing digital assets. Then came the need to ensure long-term access and we began to talk about preservation. So we talk about creating, managing and preserving, but we need to add marketing to that list. Marketing is one of the activities done when working on a digitization project, but might not be consider a major activity. Yet, if there is no marketing, then people will not find or use the materials. Marketing is critically important and thus should be listed along with creating, managing and preserving.
As you work on your projects, keep in mind the phrase "market or die." Marketing will help your projects survive and thrive.
