When I began my Little Free Library of Twinbrook (#7720) in July, 2013, I decided not to make my LFL into an OBCZ. I didn't want visitors to the LFL to not use it for fear of something which they did not understand (BookCrossing rules).
Quickly I changed my mind. As an avid and long-time Bookcrosser, something was definitely missing when I could not track books that were donated to me. I quickly started adding BCIDs to *all* incoming donations and had my Go Hunting Zone turned into an OBCZ. I never looked back!http://www.bookcrossing.com/---/733341
This is how I handle the fusion of LFL and BC myself:
1. I do not have literature about BookCrossing in the LFL itself, but I push BC *a lot* on my LFL's Facebook page. https://www.facebook.com/LittleFreeLibrary7720Twinbrook
2. I push BookCrossing *a lot* on the official LFL stewards' Facebook page.https://www.facebook.com/---/littlefreelibraryofficial/
3. I only add BCID labels to incoming book and do not "deface" them with any others stamps or labels.
4. I assume that all incoming books are mine to do with as I want.
what is the point in turning a LFL also in a OBCZ?
The answer is...to track your books...as all Bookcrossers do! :D
Be aware that LFL books have a very low "catch" rate, although I have been able to get some LFL visitors to join BookCrossing. Of course, that always makes me very happy.
Be sure to log your new LFL (with a picture) onto this LT Local page of LibraryThing. It's a great marketing tool for your LFL and makes it super easy to find. http://www.librarything.com/venue_edit.php
Click "Little Libraries", then click "Little Free Library". Add your information and then scroll to the bottom to click "Add venue".
Best of luck with your LFL adventures!
