Solution: Searching in the Amazon

(highlight to view)

As clued by the title, each row of numbers (and one letter) can be read as a 10-digit ISBN number for a book. Searching with something like Amazon.com turns up the 6 books identified by the ISBN numbers:

Be Your Own Boss At Your Current Job
We Are All Fine Here
Why New Orleans Matters
S is for Silence
Oh, the Places You'll Go!
Stitch 'N Bitch: The Knitter's Handbook

Each of the titles contains a letter:
"Be" "Are" "Why" "S" "Oh" "'N"
Strung together, the letters form BRYSON, which (when combined with the clue that the solution is a "bill") is the last name of author Bill Bryson, the solution to this puzzle.
