A nice looking new book for getting started with Squeak Smalltalk, pdf is free online, or you can order it print-on-demand from lulu. They also accept donations for the pdf.
Co-authored by local Portlander Andrew Black.
The book seems comprehensive for getting started, covering the development environment (including the Monticello package tool) as well as the language, the GUI classes, "meta" classes, etc.
This is a good year to learn Smalltalk and Erlang, with two of the best programming language books ever now available for two of the most distinguished programming languages. Every programmer would be better at whatever they do by knowing a good bit about these languages.
