However, when the site identified my country of residence as South Africa, it suggested that by registering, I could download the PDF for free for personal use. The file is only 2.3 MB, which is a quick download even on dial-up. Obviously, the NAP makes certain publications available to residents of certain countries who they feel would benefit from those books but may not be able to afford the fee.
I’d definitely recommend registering on the site to see what else they have available. I’ve had a quick look through To err is human and although I’m not a huge fan of reading books on my computer (and this one is 312 pages long), I think I’ll give this one a go. Hopefully at some point I’ll be able to put up a short review.
The direct link to the Table of Contents for the online book is http://www.nap.edu/catalog.php?record_id=9728#toc (if you’re registered with the site and live in South Africa, you should also have the option to download the PDF of the book for free).
