All of the bookcases will contain the same books. Bookcases have the ability to save bank space, because they automatically contain most books from previously completed quests and other miscellaneous books found in RuneScape. Players do not need to fetch these books from the bank to store them in their bookcase(s).
Even if you obtain a book, a quest might have to be completed in order to find the book in your bookcase. For example, The great divide requires the completion of Mourning's End Part I to be stored.
Fairy dossier (Fairy Tale 3), Economy building for dummies (Do No Evil), Philipe's note (Carnillean Rising), Ballad (Spirits of the Elid), Dusty scroll (In Aid of the Myreque), Ransom letter (Some Like It Cold), Report (Within the Light) are now reclaimable from this bookcase.
