Since then, use of the name "Webster" has been rampant. Merriam-Webster goes to great pains to remind dictionary buyers that it alone is the heir to Noah Webster. Although Merriam-Webster revisers find solid ground in Noah Webster's concept of the English language as an ever-changing tapestry, the issue is more complicated than that. Throughout the 20th century, some non-Merriam editions, such as "Webster's New Universal", were closer to Webster's work than contemporary Merriam-Webster editions. Further revisions by Merriam-Webster came to have little in common with their original source, while the "Universal", for example, was minimally revised and remained largely out of date.
