Internet searches of the Founders, Restoration Movement, Church of Christ, Disciples of Christ, Christian Church, Stone-Campbell, J.W. McGarvey, etc. Look for reprints of The Millennial Harbinger, for example.
Also, Alexander Campbell published his own edition of the New Testament, called The Living Oracles.
He published two newsletters, The Christian Baptist, for sixteen years, and The Millennial Harbinger, for over twenty years.
A summary of his theology is in his book called, The Christian System.
Do some Google searches because you might find pdf versions of his books, and sometimes you can find compilations of his Millennial Harbinger newsletters in pdf format.
Let me know when you've read all of these and you have done further research.
