Disc or Paper

I think the CD ones are better. I have my 1970 Plymouth FSM on CD as a .pdf file (Adobe Acrobat) and the file works great. The main table of contents are actually links that you can click on that will jump you right to the beginning of the section you want to look at; then you just look at the table of contents for that section and type in the page number at the bottom and press "enter". Sounds a bit confusing but actually only takes a few seconds. Once you find what you're looking for you can just print out whatever pages you need and bring them out to the garage with you. The best part is you can get the pages dirty or lost or ripped and just go print out another one in a couple seconds.
