France, Anatole. The Revolt of the Angels (New York: Crown Publishers, c1914) 348 p.

The Baron Alexandre d'Esparvieu collected many books and now, a generation later, his family has a huge and valuable library. Bibliothèque Esparvienne is under the care of a librarian, Monsieur Julien Sariette.

Endowed with business-like energy and dogged patience, Monsieur Sariette himself classified all the members of this vast body. The system he invented and put into practice was so complicated, the labels he put on the books were made up of so many capital letters and small letters, both Latin and Greek, so many Arabic and Roman numerals, asterisks, triple asterisks, and those signs which in arithmetic express powers and roots, that the mere study of it would have involved more time and labour than would have been required for the complete mastery of algebra, and as no one could be found who would give the hours, that might be more profitably employed in discovering the law of numbers, to the solving of these cryptic symbols, Monsieur Sariette remained the only one capable of finding his way among the intricacies of his system, and without his help it had become an utter impossibility to discover, among the three hundred and sixty thousand volumes confided to his care, the particular volume one happened to require. Such was the result of his labours. Far from complaining about it, he experienced on the contrary a lively satisfaction. (p. 19-20).

When books and manuscripts start disappearing from the shelves M. Sariette gets frantic. Finally it is discovered that an angel has come to Earth and wishes to educate himself. Strange events keep occurring. A very valuable book is stolen and Sariette at last goes mad. He begins hurling books out the window at passers by. Finally he is subdued and sent to an asylum.
