The largest online vendors of full-text sources to general libraries, DIALOG, Data-Star and NEXIS, are described and compared. DIALOG offers the largest number of full-text sources and the best set-building search techniques, but does not offer automatic searching of inconsistent text such as plurals or spelling equivalencies as do the others. Data-Star has the strongest European focus and information on chemistry, pharmacy and medicine. NEXIS has the most user-friendly search language and superior display features and the greatest number of unique titles.
