Union Square and Co. is an American publisher based in New York, formerly known as Sterling Publishing, which was owned by Barnes and Noble for many years before being sold and renamed in 2022.
Its catalog is broad and illustrated-heavy, covering reference, puzzles, popular science, craft, cookery, children's books, and general interest titles, and its books are frequently designed for the gift and browsing market as much as for the review pages.
It published A Field Guide to Fantastical Beasts under the pen name Olento Salaperainen, an illustrated guide to fifty mythical creatures, which is characteristic of the house's strength in producing attractive reference books for general readers.
