In the post below, on Banned Books Week, the author of the quoted excrept (the article is from the NYTimes) uses a colon twice, and a lower case letter on the next word once and an upper case letter on the next word once.
I had always thought one should use a lower case letter following a colon: it is no period after all, and so should not be accorded the dignity of one. But apparently there are at least two rules on use of a capital letter following a colon. The Times author's inconsistent use isn't one of them. And my use isn't really favored either. I don't care though and will stick to my use: a colon is not a period, after all.
