Faith Has Its Reasons (2nd ed.) by Ken Boa and Robert Bowman is a comprehensive and detailed introduction to different types of Christian apologetic methods. The authors have categorized them into Classical Apologetics (e.g. B.B. Warfield, William Lane Craig), Evidentialist Apologetics (e.g. James Orr, John Warwick Montgomery), Reformed Apologetics (e.g. John Calvin, Cornelius Van Til), Fideist Apologetics (e.g. Blaise Pascal, Soren Kierkegaard), and Integrative Apologetics (e.g. Francis Schaeffer, John Frame). It looks like you can download the book for free either here (doc) or here (pdf).
Related, Doug Groothuis has an old review of Five Views on Apologetics edited by Steven Cowan. The five views are Classical Apologetics by William Lane Craig, Evidentialism by Gary Habermas, Cumulative Case Apologetics by Paul Feinberg, Presuppositionalism by John Frame, and Reformed Epistemology by Kelly James Clark.
John Frame has written a good outline as well.
And, of course, Triablogue's own Steve Hays penned the immensely helpful "Comparative Apologetic Anatomy" way back when.
