Unfortunately there isn't a way to get rid of the black books from your inventory. However, at a certian point in the game, when the three elder scrolls are no longer needed you can sell them to Urag gro-Shub.
So I looked it up on here (the wiki) and because I sided with the vampires in dawnguard I can't sell/get rid of the other two scrolls
Actually, you can get rid of the remaining two ES selling them to the Moth priest Dexion Evicus for 1k5 each (as far as I remember).
"If the Dragonborn sided with the Dawnguard, the scroll, along with the Elder Scroll (Sun) can be sold to Dexion Evicus for 6,000 [1] after completely finishing the main quest. If the Dragonborn sided with the Vampires, it cannot be sold."

If you have a house mod, ( I use Jaggersfeld ), you can store the elder scrolls and black books on stands
Can't get rid of the Black Books in any way, but you can sell/giveaway the Elder Scrolls to the Moth Priest (6k sold or just give them to him). You can also sell them to the grumpy old Orc in the College of Winterhold Arcanium (library) for 6k. The Dawnguard main quest (kill main Vampire) must be finished to sell the scrolls thought.
