How to make reading long books ergonomic?

Sometimes I use a book holder--a little metal stand that holds your book upright rather than flat on the table, so you don't have to bend your neck down to read. It sounds silly but it can be quite helpful if you read for a long time. A popular one (not the one I have) is the http://www.bookgem.com/, but others might be better. The only problem with a book holder is that it may not hold very large or very small books very well (I have a particularly big one for that reason), and it can be hard to turn the pages when they're held down. I think the table should be higher than for a computer keyboard, because you want the book at eye level, not hand level. I'm not sure about lighting.

This may not be the answer you're looking for, but my solution to that problem was the Kindle. I had been putting off reading Stephenson's massive books (Anathem, et al) because they were just too damn heavy to hold up for the lengthy time required. I'm completely satisfied with that solution, which also has many other benefits already discussed in these pages.

There's a reason why research libraries have book stands or rests. The classic http://shop.bodley.ox.ac.uk/acatalog/Study___Desktop.html is a wallet-busting £150 -- HTTP://www.levenger.com/PAGETEMPLATES/PRODUCT/Product.asp?Params=Category=17-148%7CLevel=2-3%7CPageID=2020 -- but it works, and it's the sort of thing that might make a nice woodwork project if you're that way inclined or know someone who's handy with hardwood. Not great with folio-sized volumes, though. For those, as long as they're not perfect-bound, you're better off with angled foam cushions on each side, with thin, flat supporting cushions for when the volume's open near either end. That's something you might be able to fabricate out of upholstery foam.
