Low was an apprentice in a circulating library and briefly worked at Longman. He began his firm (1819), publishing, bookselling, and lending books on subscription, and was subsequently joined by his sons, Sampson and William. His Publishers’ Circular (competing with Bent's Monthly Literary Advertiser) formed the basis for the British Catalogue (1853–82). Active in book price stabilization and known for philanthropy, he also served as British agent for Harper & Brothers of New York.
