Logos should consider adding Christian Dogmatics and Notes on the History of Dogma by Conrad Emil Lindberg.
Lindberg’s book is not long, but packs a lot of theology into each chapter. It was published in 1922 and is in the public domain. It is similar to Schmid's Doctrinal Theology, except unlike Schmid it isn't simply a collection of quotes. However, like Schmid, it is largely a repristination of seventeenth century Lutheran dogmatics.
