@ Chicada- I do not know if there is an actual book of the dead bound in human skin, but binding books in human skin is nothing new and scientists have verified these books through DNA testing. The scientific name for binding books with human skin is Anthropodermic bibliopegy. A few Ivy League universities actually carry some of these books in their rare books collection. Harvard's Law School has three of these books, but they only allow viewings if there is an actual research need, or enough interest to hold a public viewing. Brown University also carries a couple of these in their library.
The practice was common during the 17th and 18th century. Courts would sometimes bind the case details of the trial of a convicted murderer in his or her skin. Medical professionals from the 18th and 19th century used to bind anatomy manuals in the skin of the cadavers used during experimentation. These are the books that are held in the Brown University Library. There is even a copy of "The rights of Man" and several copies of the 1793 French Constitution bound in the skin of humans conquered during the French Revolution.
