We have updated our site so you can now purchase the 2008 S4 Proceedings book of 8 papers, ~200 pages, $100 from the Digital Bond site. It also is available from Amazon.com, but you need to pay shipping at that site.

We also have a combo deal where you can purchase a copy of the 2007 and 2008 Proceedings Books for $150.

The introduction and 8 abstracts from the 2008 event are also now available online for those considering a purchase or just learning more about what happens at S4.
