Signing books for your readers is one of those nice perks of being published. Over the years I've observed most authors doing it pretty much the same way; a little message addressed to the reader by their first name, scribbled on the title page, and signed at the bottom. Like so:
Enjoy the story, and hope that nasty skin condition clears up soon!
I was so clueless when I turned pro that I thought you had to ask the publisher's permission to sign your own books (because otherwise you're defacing their property, or at least that's how I'd worked it out in my head.) I bet the editor is still laughing over that e-mail.
Some writers are great signers. Their handwriting is gorgeous, and/or they write personal notes that are as wonderful to read as their stories. A few of the artistic authors out there like Poppy Z. Brite and Stuart MacBride sometimes draw sketches in their books, which makes them instant, one-of-a-kind treasures.
Some serious book collectors prefer name-only autographed books, or what Stephen King called flatsigned editions. This is when the author signs just their name directly on a page, usually the title page. I rarely flatsign books because it seems a little impersonal to me, but there are web sites out there now like this one where you can buy them.
What most interests me is what an author puts above their signature as a sign-off phrase. "Best Wishes" is the most common, and I still use that myself. I try to use different sign-offs for each pseudonym, i.e. Blessings, Rebecca Kelly and Best Wishes, S.L. Viehl. When I branched out into vampire fiction, I wanted something different that tied into the series, which is when I came up with Always, Lynn Viehl as a sign-off.
Readers, who are some of your favorite signers, and writers, how are you going to sign your books? Let us know in comments.
