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.
