All the J Series books that used to be shelved in aisles #19 & #20 are in the process of being changed to J Fiction in aisles #16 - #18.  Most series already have titles shelved in J Fiction, either by author or series title if there is more than one author.
If you have any questions, stop by the help desk and we will be happy to assist you.
Thank you for your patience and understanding during this last phase of this change-over project.
