Information
Most of the early electronic dictionaries were, in effect, print dictionaries made available in digital form: the content was identical, but the electronic editions provided users with more powerful search functions. But soon the opportunities offered by digital media began to be exploited. Two obvious advantages are that limitations of space (and the need to optimize its use) become less pressing, so additional content can be provided; and the possibility arises of including multimedia content, such as audio pronunciations and video clips.
Electronic dictionary databases, especially those included with software dictionaries are often extensive and can contain up to 500,000

Many dictionaries for special purposes, especially for professional and trade terminology, and regional dialects and language variations, are published on the websites of organizations and individual authors.

of computer based dictionary software ranges from complex and cluttered, to clear and easy-to-use with user definable preferences including font size and colour.
A major consideration is the quality of the lexical database. Dictionaries intended for collegiate and professional use generally include most or all of the lexical information to be expected in a quality printed dictionary. The content of electronic dictionaries developed in association with leading publishers of printed dictionaries is more reliable that those aimed at the traveler or casual user, while bilingual dictionaries that have not been authored by teams of native speaker lexicographers for each language, will not be suitable for academic work.
Some developers opt to have their products evaluated by an independent academic body such as the

.
Another major consideration is that the devices themselves and the dictionaries in them are generally designed for a particular market. As an example, almost all handheld Japanese-English electronic dictionaries are designed for people with native fluency in Japanese who are learning and using English; thus, Japanese words do not generally include
furigana

pronunciation glosses, since it is assumed that the reader is literate in Japanese (headwords of entries do have pronunciation, however). Further, the primary manner to look up words is by pronunciation, which makes looking up a word with unknown pronunciation difficult (for example, one would need to know that 網羅 "comprehensive" is pronounced もうら, ''moura'' to look it up directly). However, Japanese electronic dictionaries (primarily on recent models) include character recognition, so users (native speakers of Japanese or not) can look up words by writing the kanji.
Similar limitations exist in most two or multi-language dictionaries and can be especially crippling when the languages are not written in the same script or alphabet; it's important to find a dictionary optimized for the user's native language.
