Many major works in the history of ethics are now available on-line in electronic versions. Some are simply ASCI or text files; as such, they contain a minimum of formating, but otherwise are quite serviceably. These can easily be searched or downloaded, and take up relatively little room in proportion to the amount of text they contain. Other files are in RTF, Rich Text Format, a standard developed by Microsoft that most word processors can use. These contain formatting niceties such as italics not found in ASCI files. A few files, although none currently on this list, are in Adobe Acrobat format, a very robust format that allows extensive formatting possibilities. A viewer for these files is available without charge from Adobe. Finally, some files are in HTML, hypertext markup language. 

Special note should be made of the files available at the Perseus Project at Tufts University. They are HTML files that make full use of the hypertext character of HTML. Click on any highlighted word (e.g., a proper name in one of Plato's dislogues), and you will automatically be taken to the entry for that name in a classical encyclopedia. This is the wave of the future
