We should have a logo for public bookshelves prior than just one for LFL.
I'd be very happy with that, if it included the "OBCZ"-feature of making those zones visible on the hunting pages even if there were no recent releases there; my idea was to help encourage people to seek out such sites, whether looking for books or looking for easy release spots. (I guess I assumed that LFLs were international, but in any case I'd definitely want to include any type of swap-shelf.)
We might have another logo for LFL if you really think they are something else. Or maybe, as a warning that they might be too small to be worth a visit...
Heh! I don't really see a need for lots of different logos (though a tiny "Telephone Box" logo for the UK phone-box shelves would be very, very cute). But "too small"? I guess that depends on what you're used to in book-swap shelves. Many of the OBCZs I've been to are quite small themselves, little more than a single dedicated shelf or basket, often with few if any books there. I've seen quite a few LFLs that, despite the relatively small size, were loaded plentifully with books, much more so than some of the OBCZs.
That said, perhaps some additional attributes for release zones in general wouldn't hurt, along the lines of the ones Geocaching uses to indicate whether a specific cache is winter-friendly (i.e., can you find it under X feet of snow), has limited access-hours, etc. For release zones, the approximate size (possibly rendered in number of books likely to be there?), the affiliation (there's already a field for web sites on release-zone-info pages, which might be enough), indications as to whether there are business hours or entry fees or seasonal availability involved... That kind of thing could be included in text blocks for each zone, but if there were attribute-tags tied in to search/filter features, it'd let people look for "places within 10 miles of my town that are likely to have more than 20 books in them and are open after 5 PM".
So, yeah, lots of work, for which there aren't the resources - but I can dream...
Then again, much as I love having book-swap shelves around, I also love the random-public-place releases, so for the sake of my own BC-enjoyment I don't really need any enhancements to the release-zone information. But I think that if the UBCZ-type zones were as visible on the hunting pages as the OBCZs, it might help encourage a bit more BC activity.
