Shepard & Gill, Boston (1872-1874)
Henry L. Shepard & Co., Boston (1874-1875)
William F. Gill and Company, Boston (1874-1878?)

The Shepard & Gill firm was established in October, 1872. Henry L. Shepard (1843--?) had previously been with J. E. Tilton & Co. William F. Gill had been associated with James R. Osgood & Co.

In March, 1874 the partnership between Shepard and Gill dissolved. The plates of Shepard & Gill were divided.

Henry L. Shepard & Co. became the formal successor to Shepard & Gill. Other partners in the new firm were George H. S. Driver and Charles I. Shepard. This house published several Jules Verne first editions. It also published the magazine, American Homes. It had offices in Chicago and New York as well as Boston. It appears by 1876 this firm was no longer publishing and in 1878 Shepard moved to Chicago to join the editorial staff of the Alliance.

Also in 1874 William F. Gill (1844-1917) assumed the management of the "old stand" of Shepard and Gill at 151 Washington Street and continued in the publishing business. Mr. Henry B. Cram participated in the new business. No publications of this firm have been noted after 1878.

These three related firms published a number of juvenile series.
The initials of the company which published series are noted below (*after the series' name).
