Thank you for pointing out these broken links! Actually, very little has changed in the field of polygraphy since the release of the 4th edition in 2005, and there are no current plans for a new edition. We'd like (at some point) to offer a revised and reformatted (perhaps in Open Document Format) edition, and at that time, we'll ensure that hyperlinks are up-to-date.
In the meantime, the study by Barland, Honts, and Barger may be found here:
Are there any plans to update the references in The Lie Behind the Detector. Several of the links are broken (just a few examples below) and I'm sure by now that updated material is available. Perhaps it's time to revise the whole document?
