Feist established that there has to be creativity in something for it to be copyrightable. The level of creativity required is not very high. The Court said:

   To be sure, the requisite level of creativity is
   extremely low; even a slight amount will suffice.
   The vast majority of works make the grade quite easily,
   as they possess some creative spark, "no matter how crude,
   humble or obvious" it might be.

They also use the phrase "modicum of creativity" to describe the necessary creative level.

Formatting can have sufficient creativity to qualify for copyright. Such copyright will only cover the formatting, not the underlying text. If someone were to take just the text, and format it themselves (by hand or by script), that should be OK.

Taking his exact e-text formatting? I don't know. Without comparing the originals to his version, I have no idea if his formatting was obvious and mechanical, or if it required creativity.
