Abstract: A method for automatic display of a spread in ebooks is revealed. The method includes several steps. First scan at least one paper book by a scanner to get at least one original page file with at least two original pages. Then execute a transcription suite in a computing device for transcribing the original page file into an e-book and write at least one spread event into at least one electronic page of the e-book by an input device. Next use a reader to read the e-book. The reader triggers the spread event while reading the electronic page written with the spread event. Thus the reader automatically retrieves and displays at least two electronic pages on a monitor of the reader simultaneously. Therefore the spread covering at least two electronic pages is automatically displayed on a monitor of the reader.

Abstract: A method for rating electronic books (e-books) is revealed. Acquire and save an e-book in a memory device. Set up a criterion that includes at least one standard value and a plurality of regions defined by the standard value. Compile at least one electronic label corresponding to the region by an input device and save the electronic label in the memory device. The electronic label is linked to at least one electronic page of the e-book so that the electronic label is displayed with the electronic page when the e-book is retrieved by a reading device. The present invention can be applied to rating, copyright notice, and classification of e-books. The electronic labels in visual or audio form show messages related to e-book rating, copyright notice and classification.
