Bear in mind that Kindle, and many other ereaders, are designed to automatically reflow text to fit user options like text size. Which works great for text, not so well for images like diagrams. The best think I've found for diagrams so far is to put the diagram on a page by itself and make sure the Kindle will size it to fit the entire page and even then, the diagram has to shrink to fit a 4x6 Kindle instead of an 8.5 x 11 piece of paper. This is definitely an area where the 'human factors' people ought to get involved. I think it's worth the time and effort, because many people want their manuals in many different (and often mobile) forms.
I also think intra-document linking can help a lot for devices like Kindle; page-changing is pretty rapid, but scrolling through more than a few pages costs time. I think the RedBook people ought to do a 'Greybook' about re-working documents for the Kindle ... ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN
