Okay, he doesn't sleep with them. But he clutches them to his chest for a few minutes every day. He loves his Nook, but he also loves the tactile sensation of holding a book with his favorite author's signature. So do I.
And who can really enjoy a book signing--where you get to meet one of your favorite authors, and maybe have your picture taken with her/him--when you have nothing tangible to be signed as a memento?
Until recently, this rather extreme measure was the only option. Now, Amazon offers this for Kindle owners, but you have to sign in with Twitter, and it appears to be only available for select authors and/or titles.
Here's what I plan to do, sometime before the South Carolina Book Festival next year. I'm going to make myself a Reader's Passport--essentially an update on an autograph book. (Disney offers something similar for your favorite characters.) I'll start with a scrapbook--one with a cover that strikes my fancy. I'll personalize it a bit, and make sections for my favorite genres--mystery/crime, thriller, romance, mainstream fiction, et cetera.
Then, like collecting passport stamps, I'm going to collect autographs. Most authors have either postcards or bookmarks--or something with the cover art of their book--at an author event. I'll ask her/him to sign whatever is available. If I've collected every book she/he has ever published, maybe I'll have my picture taken with him/her and add it to the page in the scrapbook.
Then if I want to sleep with my autographs, my bed will be much more comfortable. If you've switched to an e-reader, how will you have your books autographed?
