A quick Google found http://www.borrowme.com/ right away, that looks like it could be good.

We should talk at #pcto10

While the idea of a cross-province/country/borders library is neat – the idea was more something I was looking at on a local level. Early thoughts:
1. To join, you must have a book or books your willing to lend.
2. Once you're a member, you can borrow any book from any member. A website is used to track books, and handle requests for books.
3. The person who has the book and the person who ants the book meet up for the exchange – thus encouraging more community members to get to know each-other.
4. The person receiving the book has it for a guaranteed, say, three weeks. Then the book becomes available to the group again.

It eliminates the shipping costs, encourages community exchanges and connections, and helps the local community grow (Maybe something for the KW or London meetups, too?)

Thinking of how it could work:
- Users post books they have
- Others post books they want

In order to borrow a book, you have to first send a book out yourself. Here's how it works.

- The site notifies you that someone wants my book
- I ship the book to that person at my own expense
- the person marks on the website that the book has been received
- I can then request a book from someone else, who will ship it to me at their own expense

Shipping books at your own expense is to avoid having to deal with credit cards and memberships. The real trick will be limiting the distance that a book travels as that could get costly.

I averaged 1.75 hours a day (on Facebook), with an average enjoyment factor of 2. So I came to the conclusion that I’m done with Facebook. All of my correspondence is now done via email and telephone, and I am much happier. Anyway, just my experience – something to think about.

Maybe a 'Social Sunday' for all of the social media news?
