The Princeton University Press has published a book by UCLA Professor Pierre-Olivier Weill and coauthors Julien Hugonnier and Benjamin Lester on an important yet understudied type of financial markets: Over-the-Counter Markets. Over-the-counter markets are decentralized marketplaces where financial instruments, like stocks and bonds, are traded directly between buyers and sellers, without the supervision of a central exchange.

The book can be found here.
