Editorial Remarks on the Electronic Edition

The electronic book is both available as a stand-alone application which can be installed on your computer, and as a Web based compilation of material. Both the eBook and the Web material are available on the PhotoGlobe Web site (www.photoglobe.info).

While the contents of both forms of the book are the same, the navigation structure of the downloadable eBook is much more sophisticated. Thus we encourage all "power users" to download and install the eBook (see the eBooks pages of the PhotoGlobe Web site for details: www.photoglobe.info/ebooks/.

The material consists of two parts: (1) the text and the black&white photos which have been put into public domain by the US government, and (2) the colored photos supplied by various authors. While the text itself being free, the pictures, the general layout and the navigation structures are not. Thus you should not consider this particular implementation as public domain material. However, we do grant the right to use the material for educational purposes without asking and without paying any licenses. We simply ask you to make a reference to the book Web site and/or to the PhotoGlobe Web site (whatever is appropriate).

Technically speaking, this electronic book is based on Coimbra, an authoring tool for eBooks. More information on Coimbra can be found at the Coimbra Web site: www.coimbra.at.
