Just a quickie on a FEMA doc that you should read for LF. It's free, and FEMA sends it out within a week of ordering it. You can always download it and read the PDFs, but I like to have the paper and ink on my shelf.
FEMA 454 - Designing for Earthquakes: A Manual for Architects(http://www.fema.gov/library/viewRecord.do?id=2418)
It's got thump value (ie, it's a thick bugger), but don't worry - big print and wide margins make it a fairly quick read.
