Some of you may be familiar with the very helpful resources on the web pages of Richard Williams.  Richard is a sociology prof at Notre Dame, but will be retiring next year, and the original versions of his web pages will also disappear eventually.  But the good news is that he is migrating them to a new site.  You can find the details here:

Richard started life as an SPSS user, but later became a Stata user.  Therefore, you'll typically find SPSS examples only in the older resources.  But IMO, even the later notes with Stata code and output can be very helpful to anyone, regardless of what software they use.   

Cheers,
