I have sideloaded epubs books from other sites and have put them on my nook. When I search the library for the author(s) or book names, I get ZERO search results in the library, but if I go to my files and search my book folder, I can find the book there. I also have same problem with memory card that has books on it. Can anyone help me?
Based on other threads it seems that perhaps the metadata is being searched and not the file name.
Look for posts by comulsive reader. You'll have to get Calibre, then use Calibre to add metadata to epub files you get. Then it should be searchable on Nook. I think it'll work.
