From American Sphinx: The Character of Thomas Jefferson by Joseph J. Ellis:
Even if we take Jefferson at his word, that he did not copy sections of the Declaration from any particular books, he almost surely had with him copies of his own previous writings, to include Summary View, Causes and Necessities and his three drafts of the Virginia constitution.
I don't comprehend the use of infinitive "to include" here. Shouldn't it be better to substitute it by "including," which sort of like a reduced relative clause—which includes?
