Abstract—In recent years, workload of librarian has increased even more in academic or university libraries. In each library, the librarian need to do enormous thing such as guiding, searching information, sorting, arranging, inventing the books or journals, magazines… and that is the daily workload for professional librarians. In this paper, a method of identifying books placed on bookshelves in the library is described like as integrating the identification systems into the robot to carry out service works as well as to reduce service manpower. Book identification’s implementation for inventing the book or journals, magazines… focused on SIFT model in combination with Sliding Window method to recognize the spine of books on bookshelf. The experimental results were greatly potential. The accuracy of inventing with the method of SIFT is up to approximately 95% or more in the case of non-duplicated books.
