Many cosmetic glyphs are still made by players with Inscription and can be bought and sold on the auction house. Any glyphs which, prior to the patch, taught you a brand new spell are now tomes located in various places throughout the world. For example, Pet Training Manual: Fetch can now be found in from a vendor in Sholazar Basin. Once you use the manual, you learn Fetch. Some items which were formerly glyphs are now class toys. Check Wowhead for a comprehensive list of these toys.
