The Reprint Collection holds a large collection of scientific reprints arranged alphabetically by the first author's name. These are copies of articles, printed separately as overruns from scientific and technical journals, for distribution by the author(s). The collection conveniently brings together many of the writings of a single author. It often contains articles from journals not held in the general research collection. The Library is presently creating records in the online catalog to indicate that an author is represented in the collection.
The Vertical File is a subject file containing magazine and newspaper clippings, photographs, ephemeral publications, and other miscellany.
