I have recently been learning Smalltalk, mainly by going through the tutorial at gnu.org.

While it has been really helpful and I have learned a lot, I would really like an extensive smalltalk API where I could view all of the built in objects and which messages they can receive, and what they will do with those messages.

The manual has a list of all of the built in objects, but doesn't really explain anything about them. Some are obvious, like an Array, but I still don't know what all the messages are an Array understands.

There is a link to a 'class reference' here, which is generated by Smalltalk, but the link is broken. I was wondering if anyone knows of something like this hosted elsewhere, or could point me towards a similar resource.
