Little is known of French-born topographer Charles Caraccioli. But in History of British Rule in India, Edward John Thompson and Geoffrey Theodore Garratt state, "Everything to [Robert] Clive's discredit (including much that is invented)," can be found in Caraccioli's The Life of Robert Clive, Baron Plassey (London, 1775-1777). The set of four volumes, the first biography of the statesman, is part of a 40-item dedicated catalogue by London-based Peter Harrington, Europe's largest rare book dealer. Titled The Indian Sub-Continent – from the 18th to the 20th century, it has been made interactive for the first time to enable a mobile-friendly experience.

As specialist dealers, private collections are often offered to the store and they follow specialist auctions and attend fairs around the world to buy and sell rare books, too. In an email interview, owner Pom Harrington tells us that the diversity of the collection is not only restricted to the wealth of visual material, with lithographs, illustrations, maps and coloured plates but also explores a variety of subjects — from Ernest Trumpp's The Adi Granth, the first translation into English of the Sikh holy texts to the second edition of Thomas Williamson's Oriental Field Sports.
