Following the license of Greenwood Publishing Group’s imprints and titles to ABC-CLIO, Houghton Mifflin Harcourt will close Greenwood’s Connecticut office and layoff approximately 150 employees as a result, a source tells Westport Now. That source says layoffs will begin in early December. The owner of the office building “said he understands that some workers have been offered jobs in Santa Barbara, Calif., and in Colorado.”
