- Read a good book (you already know how to do that)
- Register it here (along with your journal comments), get a unique BCID (BookCrossing ID number), and label the book
- Release it for someone else to read (give it to a friend, leave it on a park bench, donate it to charity, "forget" it in a coffee shop, etc.), and get notified by email each time someone comes here and records journal entries for that book. And if you make Release Notes on the book, others can Go Hunting for it and try to find it.
Claudia Morgenstern directs me to the Wikipedia entry on BookCrossing. Some readers report that coffee shops are especially popular places to leave books. The "hunting" aspect may make this more efficient than simply leaving your book somewhere. Furthermore BookCrossing seems like an alternative means of finding dates. Here is a list of BookCrossing meet-up groups.
