In case someone is running out of CB SAT materials, here’s some useful information:

The 1995 and later CB SAT books:
@gcf101 - obviously the test changed a lot from the time those tests were written. How valuable are they for someone who plans to take the Jan 23 SAT?
Yeah, still useful. You’ll have to ignore analogy sections (and antonym sections) for very old tests (or, better yet, solve them for vocab practice), and I wouldn’t try to use them to predict your score, but they’re excellent practice. @CHD2013
To my absolute astonishment I just discovered that there exist students who have exhausted all available ETS/CB produced SAT tests of the last (2005) incarnation. And when I say all, I mean ALL: 4 CB Practice Tests, 9 CB SAT Online Course tests, all possibly obtainable QAS’s (released both in US and in Asia, plus those from the alternate dates), and I don’t know whatever else is out there “in this infinite internet space and all”. I am stunned.
There are also plenty of students who could not lay their hands on many of these innumerous materials, but crave more practice. That’s were the rusty and dusty vintage tests come into play.
I see the SAT evolution the same way you do, @CHD2013, but I also notice that with all the occurring changes there are some pervasive elements that travel through the time, sometimes morph, and then make it into the modern tests, to wit: sentence completions, vocab from analogies, long passages, tons of math questions (not of the quantitative comparison type).
Just skim through these:

When going through the math parts you’ll undoubtedly recognize what @bjkmom calls “stock questions” - they show up time and time again, like this enduring one about the average speed:

or http://talk.collegeconfidential.com/sat-preparation/877591-sat-math-question-january-2008-qas.html,
or http://talk.collegeconfidential.com/sat-preparation/1850343-help-with-math.html#latest),
or … you get the drift. The names vary (Diana, Esther, A car, Bernardo); the gist remains unchanged.
Seems, this perennial conundrum should not be forgotten, @CHD2013:

I rest my case. 
*** I have copies of these tests - the paper ones, not in the PDF form, so I ought to give credit where the credit is due - to the website which has generously posted the links.
The problem is, it’s a blog, and referencing it would be the TOS violation… I should be the last person who commits this kind of transgression. 
All I can do is to express my gratitude to the unnamed heroes - THANK YOU GUYS!
ETA. Missed @marvin100’s post, thus some repetitions. He is as usual at his best - concise and cogent. In my next life I’ll try to be just as.
@gcf101 , would you mind posting the hardest and most frequented questions since you know the SAT very well. Thanks 
Thanks guys
Any time, @CHD2013.
@ethiololita6 I wish I had time to do that…
I also wish people would continue doing what started so auspiciously - post challenging math questions in @DrSteve’s thread http://talk.collegeconfidential.com/sat-preparation/1639760-sat-math-problems-thread-p36.html.
Alas, if great beginnings always led to an uninterrupted progress, humankind would travel to infinity and beyond centuries ago. Here’s a good essay prompt to mull over: Do people need setbacks in order to improve?
Not when taking the SAT, that’s for sure!
