Elder scrolls stuck in inventory [duplicate]

I have 3 elder scrolls in my inventory that they won't let me remove. (Dragon,sun,blood). I finished dawn guard and defeated aldin which the scrolls are used for those quest lines. Why can't I remove them.


You can sell the elder scrolls to the orc in the Arcanaeum in the College of Winterhold. The elder scrolls act similar to the items that you gather for Delvin Mallory in the Thieves guild and are part of hidden quests and usually result in you selling them to certain people. This can be seen on the wiki for Urag gro-shub here.
