I just thought that I should add books that I have recently read to shelfari.com . I have an account there but have not logged in for quite a while. Now, I am stuck and don't know what to do. It seems that I cannot add a book directly by typing the author and the title of the book. I can do a search, but the book that I was trying to add (Perahu Kertas by Dewi Lestari) was not found. So there's no way to add the book to my virtual bookshelf. Oh well. Let me try another virtual bookshelf like goodreads.com.
