What does the D.W mean from Author?

"D.W." is not a standard abbreviation used in the context of authorship. It's likely a typo or a misunderstanding.

Here's why:

* "D.W." could be a shortened version of a name: If it's part of a full name, it would need more context to understand.

* "D.W." could be a specific identifier in a specific field: If it's a technical term, we would need to know what field it relates to.

Please provide more context!

For example, tell me:

* Where did you see "D.W."? (A book, a website, a document)

* What was the surrounding text?

* What is the topic of the text?
