*Bangs head on desk*

I don't know what prompted me to do it, but I went and checked some of the PASS books links on the Wayback Machine. In particular, mathematics. Pre-Algebra was there. Mathematics 2 was there. Algebra? Nope. Click on one of the algebra links and you get an error message. Oh, joy.

But, there is some good news. First, SAS just launched a new Algebra 1 course. (Scroll down a little on the page and there's a box on the right-hand side of the screen you can click on.) Second, between CK-12 and Khan Academy alone, there's lots of algebra stuff available, even without the PASS book. Don't forget, too, that you can still order the CDs for free and get the PASS algebra 1a, 1b and a third book just called "Algebra 1," plus their TEs.

Meanwhile, as soon as I can, I will check all the Wayback Machine links and make sure they are working, or pull them their corresponding HC USA page.
I was able to find the student editions of the newer PASS books on the Wayback Machine, so I have updated the links on the individual pages. (We'll see how long that lasts!) However, these links do not include the teacher editions. I highly recommend you use the information below to order the free CDs. You'll get the TEs this way. There is no guarantee how long they will be available, so do it soon. It may be that you never even use them, but they're nice to have, just in case, and you can always give the CDs away later, if you want.

Meanwhile, the World Geography PASS book apparently never made it through the revision stage. This means it is not available on the CDs, or at Wayback, like it was on the ERIC site. I have just spent over two hours trying to find a good, legal, free alternative, without success. There is a free geography book at Flatworld Knowledge, but when you click on the online free edition, all the photos are missing.

If you know of a free geography book, please let me know! I will keep searching myself and hopefully find something soon.
I have been in contact with the FLDOE representative in charge of the PASS textbooks.  They have gone back to offering the complete set of student editions and teacher editions on CD-ROM.  You may request your free copy by sending your full name and mailing address to:  BRIC@fldoe.org.  You do NOT have to be a Florida resident.  (I did confirm this.)  I will get the individual webpages that list PASS textbooks updated as soon as I can.
It has been brought to my attention that the PASS textbooks are currently unavailable again at both website locations.  It looks like the previous editions have been removed from the ERIC.gov website.  I have contacted the person in charge of the site with the updated editions to ask if/when they will be back.
