The Australian Department of Defence has issued a Request for Tender for "Provision of Computer Based E Books for Health Services at Army Logistics Training Centre". These would be used for medical training. An electronic book (e-book or ebook) is an electronic document designed to replace a printed book. The RFT does not make clear if it is for e-books, or e-book readers, the specialised tablet computers used to display the books. E-books are typically formatted in PDF and some type of HTML.
Apart from specialised e-book readers, small notebook computers (such as netbooks), PDAs and smart phones can be used. A good example of this is the OLPC, which has a rugged case, low power transflective screen which can be read in sunlight and which can be folded back over the keyboard to format a tablet computer. The OLPC would make a very useful semi-rugged and low cost e-book readers for the military.
