Release or give a book.
Hi, I was wondering how you decide whether to release your books out into the wild or gift them to fulfill a wish?
I do a lot more wild-releasing than wish-filling, but I do like to participate in the occasional RABCK or trade or bookbox or other swap-type thing. If a particular book is especially unusual, quirky, or interesting, I might check to see if anyone's wishing for it; if so, and if they're in locations that I can afford to mail to, I may dig deeper to see if they've been active on the site at all, if we've exchanged books before, if they already have a copy of that title... If everything pans out I'll send a PM with an offer to send the book, and (if it's someone I don't know or haven't contacted recently) with a deadline, as in "If you're interested, reply within the week". (That way I don't have to sit on the book indefinitely; if there's no reply by the specified time I can offer it elsewhere or just wild-release it.)
I do recommend doing at least some wild releases, even if you think you'd prefer to swap or give away books by mail. Mixing it up can keep things interesting - and may win you some new local BookCrossers!
But when you get down to it, it's a hobby so it should be for fun and enjoyment, so it's entirely up to you. Do whichever you enjoy more. Or do both.
