I was pleasantly surprised today to discover Squeak by Example, an open-source book on writing programs with Squeak Smalltalk. If you want the bleeding-edge version of the book right now, you’ll need Subversion and an up-to-date LaTeX installation, but a four-month-old PDF version is also available if you don’t want to muck with all that. Combined with Stéphane Ducasse’s compilation of free Smalltalk books, I don’t think any Smalltalk neophyte should be wanting for learning material.
