The first editions of The Harvard Classics were known as "De Luxe" sets. Most were limited-quantity print runs and some "autographed" editions (only Volume 1 is authographed) include signatures by Eliot and in some cases Robert J. Collier. The first print runs in 1909 were for volumes 1 to 25. Another print run was needed in 1910 for volumes 26 to 50 because those volumes were not selected and edited by Eliot until the middle of 1910. The first editions include Japanese vellum paper with "Eliot" watermarks (made by S.D. Warren & Co. of Boston), deckled pages, silk moire endpapers, sewn in bookmarks, and top edged gilt pages. Each was appealing to buyers for the elaborate illustrations, frontispieces, plates, portraits, facsimiles, and crimson silk page markers (features unlikely to be found in later printings). The colophon found on the ultimate page of content of first editions notes these sets were "planned and designed by William Patten" (the Book Manager at P.F. Collier & Son).
