Henry Wheatley’s 1878 monograph “What Is an Index?” gives a list of “titles of books that have given trouble to bibiographers” or been assigned to the wrong subjects:

• Maria Edgeworth’s “Essay on Irish Bulls” and a treatise on the Great Seal of the United States have both been listed under Zoology.
• A description of Napier’s bones, John Napier’s manual calculating device, has been listed under Anatomy.
• “Under the Microscope,” poet Algernon Charles Swinburne’s 1872 invective against critic Robert Buchanan, has been listed under Optical Instruments.
• A volume of poetry titled The Viol and the Lute has been listed under Musical Instruments.
• John Ruskin’s Notes on the Construction of Sheepfolds, an 1851 pamphlet on divinity, has been listed under Agriculture.
• Scottish minister William McEwen’s writings on biblical types have been listed under Printing.

Best: German naturalist Johann Heinrich Linck’s De stellis marinis liber singularis, a treatise on sea stars, has been listed under Astronomy.
