During the next few years, the NBPB became increasingly popular with the NBC and continued to produce quality literature written by black Baptists.
Most of the materials published by the NBPB were periodicals, Sunday School materials, and quarterlies.
Always a vanguard of the publishing world, by 1906, the NBPB was the largest black publishing company in America.
Unlike the NBPB, the HMB of the SBC was barely staying afloat.
Members of the "old convention" in Texas also claimed that Boyd was using his office as secretary of home missions to promote his publishing enterprises at the expense of missions by having the missionaries serve as colporteurs for NBPB literature.
The animosity between Boyd's supporters and those who wanted to see the NBPB under control of the NBC came to a head at the convention's 1915 annual meeting in Chicago.
The NBC, Inc., then sued Boyd for ownership of the NBPB. After losing the suit, the convention created its own Sunday School publishing board.
Because the Globe purchased its paper from the NBPB, located its offices in the NBPB building, and used NBPB printers, Boyd's detractors accused him of using the NBPB to further his other business endeavors and enrich himself.
The company advertised it supplies in the Globe and was housed in a building owned by the NBPB. Once again, Boyd's detractors believed he was using the NBPB to line his own pockets.
They represent the intelligent and refined Negro of the day, rather than the type of toy that is usually given to children and, as a rule, used as a scarecrow." (43) The dolls were housed and shipped from the NBPB buildings, and again, Boyd drew the ire of his naysayers.
While serving the NBPB and promoting civil rights, Boyd wrote fourteen books, the most influential of which were Baptist Catechism and Doctrine (1899), National Baptist Pastor's Guide (1900), National Jubilee Melody Songbook (n.d.), and The Separate or "Jim Crow" Car Laws (1909).
Once a slave with nothing to his name, he shaped black Baptist life through the NBPB and became one of Nashville's most successful businessmen, black or white.
