[词典讨论] 最适合通读的英语词典是？

解释最多最全的是www.oed.com (在这个网站查词第一步是点击网页左上角的home, 不然你找很久都找不到从何处开始search[点home查词时灵时不灵的])；
另一个是http://www.oxforddictionaries.com/  (这个网站的解释没有上面那个网站全，bt_4baidu大神和tsiank大神好像是从这个网站上抓的数据[我刚把他们制作的词典同这个网站上的数据做了对比]。但是我感觉从这个网站抓数据意义不大，这个网站的英英释义没有多大特色。目前不知有没有大神从www.oed.com上抓数据呢？)

举个例子来说吧，在以上两个网站同时查high，在www.oed.com上查的到high做名词时有drugs的意思，可是在http://www.oxforddictionaries.com/ 却找不到。
谁能告诉我上面那两个网站之间究竟有何关系？怎么它们搜出来的结果有些不同呢？

Unlike most English dictionaries, which only list present-day common meanings, the OED provides a detailed chronological history for every word and phrase, citing quotations from a wide range of sources, including classic literature and cookbooks. The OED is famous for its lengthy cross-references and etymologies. The verb “set” merits the OED’s longest entry, at approximately 60,000 words and detailing over 430 uses.No sooner was the OED finished than editors began updating it. A supplement, containing new entries and revisions, was published in 1933 and the original dictionary was reprinted in 12 volumes and officially renamed the Oxford English Dictionary.Between 1972 and 1986, an updated 4-volume supplement was published, with new terms from the continually evolving English language plus more words and phrases from North America, Australia, the Caribbean, New Zealand, South Africa and South Asia.In 1984, Oxford University Press embarked on a five-year, multi-million-dollar project to create an electronic version of the dictionary. The effort required 120 people just to type the pages from the print edition and 50 proofreaders to check their work. In 1992, a CD-ROM version of the dictionary was released, making it much easier to search and retrieve information.Today, the dictionary’s second edition is available online to subscribers and is updated quarterly with over 1,000 new entries and revisions. At a whopping 20 volumes weighing over 137 pounds, it would reportedly take one person 120 years to type all 59 million words in the OED.

这部词典我买了三本，从头到尾看过一遍，现在仍然爱不释手。
