Spellbooks are generally a support archetype for Spellcasters. They excel at searching and boosting Spellcaster monsters with Prophecy monsters acting having the most synergy with them. With all that, the only thing lacking from Spellbooks/Prophecy right now is a boss monster to invest their support in.

While Spellbooks will cover all your support, Silent Magicians will be your main beaters. Summoning the Non-LV Silent Magician should be done by tributing a Spellbook Magician of Prophecy after you have used up his search effect. You should then try to protect her and keep her on the field so that you can activate Spellbook of the Master and Spellbook of Fate. Spellbooks are really good at maintaining their card advantage, so you should have no problem keeping Silent Magician above 2000 attack if used properly. If ever she does get destroyed you can special summon Silent Magician LV8 which has 3500 attack and is immune to your opponnet's spell effects.
Silent Magician is also extremely valuable in a mirror match and when dueling against other meta decks because she can negate key cards like Spellbook of Fate, Masked Change, and Ties of the Brethren.
Searching and thinning your deck is what this deck really excels at. Most cards in this deck has some form of search function to get Spellbooks or Prophecy monsters out from your deck.
When searching monsters this deck excels at special summoning your searched monster directly from the deck onto the field. Once per turn, Fool of Prophecy can mill any Spellbook spell card from your deck helping you reach his effect's activation condition. During the end phase when you have 5 or more Spellbook spell cards in the graveyard you can special summon a level 5 or higher Spellcaster from your deck. The best thing you could do with this is special summon Reaper of Prophecy, and then with Reaper of Prophecy search out a Spellbook from your deck and special summon Dark Magician of Chaos. Dark Magician of Chaos can then retrieve a spell card from your graveyard, this combo results in a plus 3 in card advantage.
Summon Blizzard Princess by tributing Spellbook Magician of Prophecy or any 1 Spellcaster-type monster. She effectively shuts down your opponent's backrow for the rest of the turn after she is summoned allowing you to attack safely. Some easy ways to summon Blizzard Princess include using The Tricky or Legion the Fiend Jester as tribute fodder so that you can tribute summon into Blizzard Princess during the same turn.
Use Strength of Prophecy's effect to boost the attack of a Spellcaster-type monster on your side of the field by 500. Usually his effect will be used on himself first so that you can boost him enough to keep him on the field. His effect is also a good way to recycle Spellbooks in your graveyard back to the deck, which can then be searched by Spellbook of Secrets or Spellbook Magician of Prophecy.
Use Spellbook Library of the Crescent to search your deck for Spellbook spell cards. You can only use Spellbook Library of the Crescent if you have no Spellbook cards in your graveyard and the card that gets added to your hand is chosen at random by your opponent. But it could still be worth running this card to fuel your graveyard without losing card advantage. This could also help in some situations where your graveyard runs out of Spellbooks because of Spellbook of Fate and/or Prophecy of Strength removing them from the grave.
To maximize the use of your Spellbooks you also want to retrieve them for reuse. Dark Magician of Chaos can retrieve a spell card from the graveyard everytime he is summoned. Spellbook of Eternity can retrieve a Spellbook card banished by Spellbook of Fate.
Spellbook of Life can be used to revive a Spellcaster-type monster from your graveyard, the best targets are Dark Magician of Chaos, Reaper of Prophecy or Fool of Prophecy depending on the situation. Dark Magician of Chaos is the easiest target because he simple allows you to retrieve a spell card when he is summoned. Reaper of Prophecy is good if Dark Magician of Chaos is still in your deck and you have 5 Spellbooks in your graveyard, you also get to search a Spellbook from your deck. Fool of Prophecy is a great target if you want to gain a lot of card advantage while Dark Magician of Chaos and Reaper of Prophecy are still in your deck.
Spellbook of Fate has varying effects depending on the number of Spellbook card you remove from play as cost.
Spellbook of the Master is a good card to use in any Spellbook deck, because it can use the effect of any Spellbook normal spell in your graveyard. This bypasses the the Spellbook's activation condition. Also since all Spellbook cards have a hard once per turn effect, Spellbook of the Master allows you to practically activate it's effect twice in one turn.
