The most expensive sale in AbeBooks' history occurred in February 2015 when a rare ornithology book printed in 1765 sold for $191,000. This sale took online bookselling into six figures for the first time. The book's Italian title can be translated and shortened to A Natural History of Birds (images are displayed below)
Published in Florence, this five-volume Italian book contains 600 beautiful hand-colored engraved plates of birds. Commissioned by Maria Luisa, the Grand Duchess of Tuscany, the book took 10 years to complete. This copy's fine condition enhanced its value along with the fact that it is a scarce book - only 10 complete copies had been offered at auction in the previous 40 years.
