For referencing ability the original work's page lay out has been retained. HTML pages have a load time - for this reason some of the chapters have been split between more then one HTML page. We have strove to keep each HTML page's load times about 80 seconds.
Plain text loads faster then pictures - so the less pictures the more pages in each section.
Because of this I have left out special character - like umlauts and so forth. Though these are on most machines today - they are not on all. When they are not they result in the creation of a garbled and unreadable mess. In the original hard copy all words were properly marked. HTML 2 was used.
