Each e-book is represented by its own spine. The library owner can define the size, color and font on each spine. So spines can be color coordinated with the other decor in the room where the virtual bookshelf will be located. Once the virtual bookshelf is created it is placed on a blank wall. E Ink manufactures digital ink .
Digital ink is sprayed onto any surface such as a blank wall for displaying a virtual bookshelf.
The virtual bookshelf is loaded into the digital ink. Digital ink displays the virtual bookshelf on the wall with no additional electricity until the bookshelf is changed and reloaded onto the wall. For those wanting book displays for access to their collection, the virtual bookshelf software offers an additional advantage. Since the software is a database, e-books could be sorted and redisplayed on the virtual bookshelf by color, size, author, title, and, if more complete cataloging is in the database, subject, call number, date. The virtual bookshelf could be used for browsing with additional capabilities in the software.
