[This is my second post on publishing a technical book. If you’re not sure if you should write a book, check out part 1.]
You’ve probably heard of some book publishers before like Simon and Schuster or Random House. Those companies don’t usually get involved in smaller technical books. Instead there are several specialized publishers for books in the tech field, the biggest are O’Reilly, Manning, Pearson, and Chapman and Hall, along with some specialized ones like A Book Apart (which publishers short books).
