Alright.. so i didnt know if anybody know this already or has experienced it but there is a glitch or something that duplicate books after the 1.9 patch on consoles... Here's the details on how i found out:

My bookshelf in Whiterun was full and i was moving to Solitude.. so i took all my books using the "take all" button and and for some reason few books were left (3)... So i clicked the bookshelf but there wasnt any books listed and as soon as I exit that menu the books left on the shelf would vanish.. so i tried restocking my bookshelf (full) and tried it again.. didn't work that time so i tried another and it worked but this time only 1 book was left. I then decided to read it not activating the bookshelf menu and took it. Checked my inventory and it was duplcated O_o

Sometimes you need 1 or more book restockings for the glitch to leave books and it leaves random book/books not a specific one or in specific order. Sometimes it leaves most of the books. Anybody had this experience?
