Okay, after scratching my brow and consulting some more tech-savvy people in the IFLS office, I realize that I spoke too soon in promising the copies of the Summer Library Program video public service announcements. We haven't figured out how to do it yet.
On a brighter note, I did find out that you can download the PSAs from the website: http://www.cslpreads.org/. Just go to the page, and there is a place at the bottom of the page to log in. You can register, and then log in, and you will have access to the PSA.
I hope this helps!
