I've been reading a lot of non-fiction recently: literary essays, humor, reportage, etc.
Russell Baker's Looking Back: Heroes, Rascals, and Other Icons of the American Imagination (2002). Essays originally published as book reviews in the New York Review of Books. The subjects are as diverse as the title implies: William Randolph Hearst, Joe Mitchell, Joe Dimaggio, JFK, LBJ, Nixon, Eugene Debs (and his loopy biographer Marguerite Young), etc. Baker's a talented writer with good insights on whatever he chooses to write about. Highly recommended.
But Do Blondes Prefer Gentlemen?: Homage to Qwert Yuiop and Other Writings? (1986) by Anthony Burgess. A wide-ranging collection from the "Clockwork Orange" author. There's lots here on books and writers, language, music, film, art, history, politics, etc., all of it very smartly-written (I confess, I had to look up the definition of about two words per page, on average).
Uncivil Liberties (1982) and With All Disrespect: More Uncivil Liberties (1985) by Calvin Trillin . Short topical humor essays, somewhat dated (a lot of Reagan-era references), but a fine, droll wit throughout.
Killings (1984) by Calvin Trillin. The rare non-funny Trillin book, although there are subtle humorous asides here and there. I recently re-read this again after many years, and still find it very good. A collection of sixteen articles, originally published in The New Yorker between 1969 and 1982, concerning murders, possible murders, accidental deaths, suicides, etc. There's not much suspense or mystery here, more a survey of American life conducted by a writer with a very sharp eye.
