I found these settings worked pretty well:
Code:
k2pdfopt -p 50-52 -mode copy -c- -m .25,.42,.25,1 -t -om 0.25 -as -ocr t input.pdf -o output.pdf
The -p 50-52 just tries it out on pages 50-52 as a trial since the book is very long (you can remove this once you want to try it on the whole book).
The -mode copy defaults to copying the source page size
The -m arguments ignore the left 0.25 inches, the top 0.42 inches, the right 0.25 inches, and the bottom 1 inch of each source page
The -t trims to the text
The -om adds a small blank border to the output edges (0.25 in)
The -as auto-straightens (de-skews) each page
The -ocr t uses Tesseract OCR
