However, in the end only three "Additions" volumes were published this way, two in 1993 and one in 1997, each containing about 3,000 new definitions. The possibilities of the World Wide Web and new computer technology in general meant that the processes of researching the dictionary and of publishing new and revised entries could be vastly improved. New text search databases offered vastly more material for the editors of the dictionary to work with, and with publication on the Web as a possibility, the editors could publish revised entries much more quickly and easily than ever before. A new approach was called for, and for this reason it was decided to embark on a new, complete revision of the dictionary.
