Houghton Library houses the historical archives of Houghton Mifflin Co., including editorial correspondence, contracts, and 19th- and 20th-century business papers, and they are open for research. The archive does not include copies of Houghton Mifflin’s publications.
There are several online finding aids for the cataloged parts of the collection in HOLLIS for Archival Discovery. Search Houghton Mifflin (without quotation marks), and limit the results to Houghton Library using "Refine My Results."
Much of the 20th-century part of the archive remains uncataloged, but readers are welcome to look at all parts of the collection in the Houghton Reading Room.
We cannot make photocopies of uncataloged material and are unable to search for particular items in the unprocessed parts of the collection due to its size and because much of the collection is stored off-site.
