The idea is that those who already have knitting books listed within their library can join the group, add any titles to the group library that they wish to virtually 'share' (as in "I have a copy of this, I can give you a review/look up the yarn on page 64 if you've lent your copy out/
I'm BoPeep on LT if anyone wants to message me there, and I can keep track of interested parties through comments here if you give me your LT name - we don't yet know when Tim plans to implement this or how many members he wants to try it out with, but there was mention of 'reaching critical mass' so there's probably some kind of minimum.
Edit: Message from LibraryThing
Okay, Bopeep, you're on. I was looking first for groups that would use the forum capability, which you guys probably don't need if you have here, but the number of people coming from this group to LibraryThing is REALLY impressive. You guys are a pilot group.
Here's the deal:
Free year's membership to any member who hits 50 books cataloged [these don't have to all be knitting books AFAIK]. Members should email me their LJ and LT user names.
I'll send you the group URL as soon as it's ready (Monday?). I think you'll have groups for a day before they go live--maybe more. Anyway, when I announce groups I will point to you.
Looking forward to seeing your books!

He's on LJ as librarythingtim incidentally. Can I also point you to librarything, library_thing, and thingology if you don't already know about it?
