感谢楼主!为了使用POED,了解了一下其源流。
从大大哥到小小弟:
Oxford English Dictionary (OED)
a historical dictionary
Shorter Oxford English Dictionary (SOED)
an abridgement of the full work that retains the historical focus, but does not include any words which were obsolete before 1700 except those used by Shakespeare, Milton, Spenser, and the King James Bible.
The Concise Oxford Dictionary of Current English (COD)
aims to cover current English only, without the historical focus
