NOTE: Primarily the PDF CtPbookV1.pdf is made to be printed as a book. Other versions of this PDF are modified to be better viewed on screen - whilst another is already pre-printed in PDF format as a 2-up meaning that there are 2 pages per A4 Landscape oriented page to make for easier printout (on A4 paper) for personal use.
NOTE: The primary book version was made for printing as a book so it was not optimised for onscreen viewing or personal printout. This version 2upbookctpv1.PDF has been reprinted (Distilled) via Acrobat so that there are now 2 pages per A4 page in Landscape orientation (rather than usual Portrait orientation) so as to make personal printouts for reading much easier. The same effect could be obtained by using the original CtPbookv1.pdf and printing that via your desktop printer driver so as to have 2 pages per page (if possible).
