I came across this interesting resource:
Derashot Shedarashti: Sermons of Rabbi Norman Lamm.
Here is a collection of the sermons given by Rabbi Lamm from 1951-2004. Included are his handwritten and typed notes. It is a veritable trove for the armchair historian interested in many aspects of American Modern (I mean "Centrist") Orthodoxy in the latter half of the 20th century, and undoubtedly a treasure trove for the critics of such.
It contains everything from a tribute to Albert Einstein on the occasion of his 75th birthday, to critiques of Conservative Judaism to reflections on the Nixon tapes, to more conventional inspirational and learned derashos, and being of that time period, much usage of the term "Please G-d."
Here, for example, is an excerpt of a sermon delivered in 1955 in honor of the 750th yahrzeit of the Rambam.
