Coraz więcej słowników oferowanych jest w formie elektronicznej. Oznacza to, że znika problem ograniczenia objętości w tradycyjnych słownikach drukowanych, których rozmiar wymusza selekcję zawartych słów pod względem przydatności dla użytkownika. Dlatego słowniki internetowe oraz te na płytach CD mogą zawierać więcej słów, wyrażeń i znaczeń, również tych bardzo nieformalnych i specjalistycznych.
