Purchasing the PHB will only give you compendium access to the information in the PHB. At this time, spells that are specific to modules are only listed as handouts in those modules, and do not have a compendium equivalent. If you upgrade to pro-level, you can use the Transmogrifier to copy those handouts from a PotA game into whatever game you would like, but they still won't be drag and drop for the character sheet. There are posts in the suggestions forum that ask for these items to be added to the compendium (example, <a href="https://app.roll20.net/forum/post/4890588/any-plans-on-adding-npcs-and-new-monsters-from-modules-to-the-compendium/?pageforid=4890588#post-4890588" rel="nofollow">https://app.roll20.net/forum/post/4890588/any-plans-on-adding-npcs-and-new-monsters-from-modules-to-the-compendium/?pageforid=4890588#post-4890588</a> ) so perhaps adding your voice there might help.
