According to Craig Morgan Teicher at Media Bistro's eBookNewser:
"Learning A-Z, makers of preK-6 educational resources, and Language Technologies, the company behind Readsmart, have announced a partnership to bring 120 preK-6 reading apps to the Apple App Store for use on the iPhone and iPod Touch."
According to a Learning A-Z press release, the new apps will be available at iTunes by searching for the keywords Learning A-Z or Reading A-Z. I wasn't able to find the apps following their directions, but I did find reading apps using the keyword "LAZ." A few of the LAZ titles you can check out include the free apps "Making Pizza" and "Discovering Dinosaurs."
