I work with a book printer, Black Classic Press, in fact I'm a reseller of their services, https://aalbcprintsbooks.com, but I've only had a few clients.
There one client I worked with a Brother, Dr. David Covin, who is also a publisher. EVERY business involved with the production of his book (Raisins in Milk), writer, editor, book designer, book cover artist, printer, distributor, publisher, book reviewer, promotion and advertising, and bookseller is Black. In fact, when his book became an AALBC bestseller, he printed AALBC's Bestseller's seal on the book's cover for his second print run! Dr. Covin is not the only author you utilizes Black-owned businesses to produce their books.
Imagine, if every indie author did this, rather than giving Amazon all their business?
Actually the Black book ecosystem is much stronger outside America. I've work with publishers like African World Press who has offices all over the word. Cassava Republic Press is based in Ghana and the UK. Once of their books In Dependence by Sarah Ladipo Manyika has sold over 3 million copies worldwide.
We don't heard about these business and books because we have no significant voice and we do not control the narrative. White folks decide which Black writers are worthy and then every one else, including some Black book sellers follow the white lead. Part of the reason people echo what white folks say is important is because the books that make the bestseller's lists and get the awards are the ones that sell the most and make the most money.
It is simple, we must support the business in the black Book Ecosystem, it is the only way our voices will be heard, at least in this country (America).
Right now there is a effort to get Big Five publishers to publish more books by Black writers. This is tantamount to asking publishers to produce books that will lose money for them. The books will lose money not because they are not worthy, but book sellers don't have a clue how to sell these books.
Sure it is easy to sell Michelle Obama's book or an Anitracist book (right now). How would they sell the upcoming novel from Africa Work Press, Maasai: A Novel of Love, War and Witchcraft in 19th Century East Africa by Elliot Fratkin? ...and that last book was written by a white guy 🙂
