About 10 years ago MERLOT acquired the KEEP Toolkit from the Carnegie Foundation. KEEP was a rudimentary web development application used by thousands of educators to create web-based teaching and learning materials. Over time, MERLOT refined the Content Builder with a better “MERLOT-looking” user interface as well as improved user functionality. One of the early additions to the CB was the requirement that all CB-developed assets that “go public” must have a Creative Commons (CC) license. (MERLOT does not dictate which license a user must declare.) Any user can create a web page or site in Content Builder but until they make it public with a unique URL (and CC license), it is “private.”
