Short answers, pulled from the story.
Greenwood Publishing Group was founded in 1967 as Greenwood Press, Inc. by Harold Mason, a librarian and antiquarian bookseller, and Harold Schwartz, who had a background in trade publishing. The company was based in Greenwood, New York.
On the 1st of October 2008, ABC-Clio and Houghton Mifflin Harcourt announced an agreement giving ABC-Clio a perpetual license to use the Greenwood imprints and publish its titles. The Westport, Connecticut office at 88 Post Road West closed, layoffs began in December 2008, and the full transfer completed during 2009.
Bloomsbury Publishing is a British publishing house that bought ABC-Clio in December 2021, acquiring Greenwood and its imprints in the process. Since 2021, ABC-Clio and its suite of imprints, including the Greenwood labels, are collectively imprints of Bloomsbury.
During Robert Hagelstein's twenty-seven year presidency, from 1973 until his retirement at the end of 1999, Greenwood published more than ten thousand titles. Under his leadership the company shifted from reprinting out-of-print works to producing new scholarly, reference, and professional books.
Greenwood Publishing Group's imprints included Greenwood Press for reference works, Praeger Publishers for scholarly and general-interest books, Libraries Unlimited for professional works for librarians and teachers, Quorum Books for business and law titles, Greenwood Microforms, and Greenwood Electronic Media. After the ABC-Clio transfer, Praeger Publishers, Praeger Security International, and Libraries Unlimited became stand-alone ABC-Clio imprints.
The Greenwood name stopped being used for new books in 2023, following Bloomsbury Publishing's acquisition of ABC-Clio in December 2021. The name had been in use since the company's founding in 1967.
