Another old book on books, this time from Project Gutenberg:
The Enemies of Books, by William Blades 
It breaks down the various threats to the survival of books by topic (fire, water, neglect, vermin, collectors, children…) and then lists a succession of anecdotes about collections destroyed in this way. Surprisingly interesting, in some cases, if a bit depressing; it’s interesting to know what has been lost over the years but is still known about. I wrote last month about the monastic libraries being dissolved at the Reformation; here is a contemporary writing about what happened to their contents:
A greate nombre of them whyche purchased those superstycyouse mansyons reserved of those librarye bookes some to serve their jakes, some to scoure theyr candelstyckes, and some to rubbe theyr bootes. Some they solde to the grossers and sope sellers, and some they sent over see to ye booke bynders, not in small nombre, but at tymes whole shyppes full, to ye wonderynge of foren nacyons. Yea ye Universytees of thys realme are not alle clere in thys detestable fact. But cursed is that bellye whyche seketh to be fedde with suche ungodlye gaynes, and so depelye shameth hys natural conterye.
I knowe a merchant manne, whych shall at thys tyme be namelesse, that boughte ye contentes of two noble lybraryes for forty shyllynges pryce: a shame it is to be spoken. Thys stuffe hathe heoccupyed in ye stede of greye paper, by ye space of more than these ten yeares, and yet he bathe store ynoughe for as manye years to come. A prodygyous example is thys, and to be abhorred of all men whyche love theyr nacyon as they shoulde do. The monkes kepte them undre dust, ye ydle-headed prestes regarded them not, theyr latter owners have most shamefully abused them, and ye covetouse merchantes have solde them away into foren nacyons for moneye
