Developing applications for IE 8

Question

Anyone know of any good references for building applications for IE 8? I found this http://www.apress.com/book/view/1430228539 (but not yet released)

for example: I would like to build a simple toolbar app that records visited websites. That possible?

Or are they other suggestions on how to build this type of application?

MSDN seems like the ideal source.
