No one is really sure, but it seems likely that by the middle of the century all dictionaries will be in electronic form. Now that space issues are less important, dictionaries will be able to include more encyclopedic information such as biographical and geographical entries, names of famous books and historical events. They will also be able to be updated more rapidly. Multimedia will play a part with audio pronunciations, illustrations and video present for many words. But the general idea of a dictionary - a resource that provides explanations of words and how they are used - will remain the same.
