Grosset & Dunlap

(Text below adapted and modified from Wikipedia)

Grosset & Dunlap is a United States book publisher founded in 1898.

The company was purchased by G. P. Putnam's Sons in 1982 and today is part of the British publishing conglomerate,
Pearson PLC through its American subsidiary Penguin Group (USA).

Grosset & Dunlap is historically known for its photoplay editions and juvenile series books such as the Hardy Boys,
Nancy Drew, The Bobbsey Twins, Tom Swift, Cherry Ames and other books from their former ownership of the
Stratemeyer Syndicate (currently owned by Simon & Schuster). For collectors of Edgar Rice Burroughs the company is
particularly significant, because beginning in 1918 with
A PRINCESS OF MARS Grosset and Dunlap became Burroughs'
primary publisher, with a total of 47 titles printed.  They would continue publishing at least nine of the Tarzan novels into
the late '60s.  

In the 1970s and 1980s, the company's Charter Books (also known as Ace Charter) imprint published mystery fiction.
Most notably for ERB fans, they published six paperback reissues:

1. The Bandit of Hell's Bend
2. The Deputy Sheriff of Commanche County
3. The Efficiency Expert
4. The Girl from Farris's
5. The Girl from Hollywood
6. The Oakdale Affair
