The ephemera consists of autograph copies, facsimiles, photocopies and printed material. Two boxes contain the autograph copies of letters written to and from Francis Lieber, probably in preparation for the publication of his collected letters; many of the copies were made by Matilda Lieber. The largest portion of the series is comprised of printed pamphlets, catalogs, clippings, articles, newspapers and journals; this material is in English, German, French, Italian, and Latin; some of this material contains minimal autograph notes by Lieber.
