Online Dictionaries
A Chinese-English dictionary of Chinese characters based on major modern and classical lexicographical sources. Includes pronunciations for Mandarin, Cantonese, Hakka, and other Chinese languages in mostly used phonetic systems. Character data sheets provide links to the Chinese-English dictionary, other online dictionaries and databases, and lexicographical indices. Allows characters to be found by English, Mandarin, Cantonese or Hakka pronunciation, radical and stroke count, four corner, and other indexing systems.
This Chinese/English dictionary provides a searchable interface for the CEDICT dictionary originally put together by Paul Denisowksi. Searches can be conducted by Chinese (using either the GB, Big5, or Unicode encodings), pinyin, or English. Results will show the Chinese word, the pinyin representation of the word, and the English definition. You can choose to have the Chinese characters appear as GIF pictures. You can also click on the pinyin to hear how it is pronounced.

Chinese character dictionaries
Most of the major Chinese character dictionaries on the web are interlinked at a character-to-character level, allowing visitors to quickly jump across dictionaries to check the same character entry without having to search again for the character. Find a character in any of the above dictionaries and you can follow the blue links, jumping between more than a dozen dictionaries spread across seven countries and four continents. (I once gave a brief talk on this phenomenon.)
