Can I Erase Spells from my Spell Book

[mage7]

hey all, this one is confusing me too

I've recently upgraded my spell book to 3/3. Doesnt this mean I should have maximum available slots available for spells and scrolls?

I have one 'slot' open in Order, a couple in Distortion, and a few in CHaos. I just landed in the Elven lands and am finding lots of scrolls and my book shows that I am at like 27/15 now -- in other words I should have 12 extra somwhere that I need to sell. Yet I cant find them! So dont know how to sell them. Also, some of them are *new* spells that I havent inscribed yet and I really waynt to, like Teleport and some others. I dont know where they are going, how to find them (even If I buy them) and thus cant scribe them. Again, spellbook is at 3/3 so I would think there would be room to scribe the missing scrolls?

Thanks!
