If it's good enough for Amanda A. and Heather, it's good enough for moi!
Hardback or trade paperback or mass market paperback? I definitely prefer trade paperback. They're comfy, easily carried around, and the print size is just right. I abhor hardbacks in general since they're harder to carry around and uncomfortable to hold, in my opinion.
Amazon or brick and mortar? Either. I love Amazon for the recommendations and ease with which I can flutter around between genres with a simple click. And I adore my wishlist. I love bookstores for the ambiance. I like fondling the books, wandering around, and if there's a coffee smell wafting, I'm even happier.
Barnes & Noble or Borders? B&N. I can't say that I've ever even been to a Borders.
Bookmark or dogear? If it's a book I don't plan to keep, or if it's already been well-loved, or if it's a school book, I don't mind the dogear approach. I generally use receipts, sticky notes, and some proper bookmarks for bookmarking.
Alphabetize by author or alphebetize by title or random? Random. I generally group my books into zones and genres. For instance, the 3 bookcases in my living room are for my mom's books as well as my classics and my keepers. The very large bookcase in my bedroom is for books I haven't read yet, and it's somewhat organized by genre: classics, children's/young adult, literary fiction, graphic novels, brain candy, etc. It works!
Keep, throw away, or sell? I keep all classics and the books I think I'll re-read. Otherwise I generally donate them if possible or sell them to Half-Price Books so I can start the mad cycle all over again.
Keep dustjacket or toss it? Keep! Who seriously throws away the dust jacket? Why would someone throw away a part of a book? A pretty one at that!
Read with dustjacket or remove it? I take it off 1) for comfort 2) to preserve the pristine condition.
Short story or novel? Although I do enjoy short stories, I generally prefer the novel. I like something that I can get totally involved in, and short stories generally don't fulfill me.
Collection (short stories by same author) or anthology (short stories by different authors)? Meh. Doesn't really matter, as long as I'm in the mood.
Harry Potter or Lemony Snicket? Harry Potter all the way! While I think Lemony is charming, the books are too formulaic for me to read them in any sort of quick succession (re: more than 2 a year). Harry is charming and delightful and suspenseful and fantastic. Long live Harry! At least through Book 7. Please don't kill him, J.K.!
Stop reading when tired or at chapter breaks? I try for chapter breaks. It just feeeels right.
"It was a dark and stormy night" or "Once upon a time"? Once upon a time! I am a fairytale specialist, ya know. (Actually, I rarely mention my academic interests, but one of my specialties really is the oral tradition. Shut up Todd and Os.)
Buy or Borrow? I love to buy, but I neeeed to borrow.
New or used? It really doesn't matter, as long as it's in decent shape. I like buying used for the simple fact that the book has a history, and sometimes I find little artifacts from the previous owner.
Buying choice: book reviews, recommendation or browse? All of the above. Although, I have to admit that I read far fewer "real" book reviews anymore (from reading publications and whatnot). The reviews I favor are those of close friends and bookish peeps from blogs and my online groups.
Tidy ending or cliffhanger? The messier the better! I love ambiguity and all things unresolved.
Morning reading, afternoon reading or nighttime reading? I rarely read in the morning for the simple fact that I'm usually not aware enough to do so. I favor afternoon reading...sprawled out on my bed with the TV on mute. Evening reading is a rarity if I'm tired or before bed. I guess that explains why I get so little reading done during the semester.
Standalone or series? Stand alone. I have loved a great many series in my time (Stephenie Meyer's Twilight series, Harry Potter, Lord of the Rings, etc.), but they're a rarity for me in the grand reading scheme of things.
Favorite book of which nobody else has heard? I Am Madame X, by Gioia Diliberto. It's sort of in the same vein as Tracy Chevalier's Girl with a Pearl Earring. It's the fictionalized story of the subject of one of John Singer Sargent's most famous paintings, Portrait of Madame X.
Favorite book(s) read last year: The New York Trilogy (Auster), The Book Thief (Zusak), The Road (McCarthy), Twilight and New Moon (Meyer), and a bunch more.
Favorite books of all time? An assload. A few include: What I Loved (Hustvedt), The Hours (Cunningham), Great Expectations (Dickens), The Waste Land and Other Poems (T.S. Eliot), Cider House Rules (Irving), The Lord of the Rings (Tolkien), Pride and Prejudice (Austen), and a bunch more.
