It might almost be shorter to list the authors I didn't like.........but
Heinlein, Clark, Asimov, Zelzany, McCaffrey, Bradley, Norton, Blish, Bujold, Brust, Anthony, and the rest of the "classic" science fiction and fantasy pantheon as well as lots & lots of the newer authors (defined as started writing AFTER 1985 or so). Howard's Conan books come to mind.
Burroughs, Wells, and Doyle in really classic literature - as well as Clemens/Twain for turn of the 19th and early 20th century.
Auel - although after #3 the book seemed to be more prehistory recipes, description, and sex scenes with foreshadowings of future "plot" details than the original Clan of the Cave Bear promised. It's not that it is BAD - it just isn't quite the same.........
Then there is Lackey, the one Stephen King book called something like "Eye of the Dragon" that was fantasy and not horror, Hamilton (Merry Gentry - what is taking so long for her to get pregnant - you'd think the reader would be at risk of pregnancy symptoms after reading about all the bedroom activity!), Weber's Honor Harrington, Harris (Charlaine, if anyone doesn't recognize Sooky Stackhouse's author), and a whole new slew of mystery writers that I have discovered since moving to a new town with all new libraries..........
Judith Martin's Miss Manners, of course, Jeanne's Bridezilla books, biographies written with a touch of humor, quilt books, knitting books, embroidery books, sewing books, and anything else sitting around that looks interesting and is in English. I don't remember my Spanish lessons well enough to read anything that hasn't been translated............
I almost forgot to add The Chronicles of Narnia, The Lord of the Rings & The Hobbit, and even Jonathon Swift's satires - Jack London, Defoe's Robinson Crusoe(sp?), The Swiss Family Robinson, Nancy Drew, Cherry Ames (a nurse around WWII and just after), and half a thousand more whose names I cannot recall at this time.
If I owned one copy of every book that I ever read - I'd need at least one more house to put them all in. Even if they were all on CDs, the stack would be pretty big.
