NOT A TEACHER
(1) It means "in the exact sense of the word." (Source: The New Oxford American Dictionary, 2001.)
(2) Such is a pronoun and needs an antecedent (it needs to refer to some noun in the sentence). (Source: A Dictionary of Modern American Usage, 1998. Bryan A. Garner.)
(3) This is a small village. There is no hotel as such. ("Such" refers to "hotel." That is, there is no business that is officially a so-called "hotel." But Mrs. Parser, a widow, will let visitors stay overnight at her home for a small fee.) (I credit The New Oxford American Dictionary for this idea.)
(4) "If this is not genuine champagne, it should not be labeled as such." That is, if it is not real champagne, the label should NOT have the word "champagne."
(This example comes from the online Macmillan dictionary.)
(5) "I am interested in getting a good photograph, not in the castle as such." (That is, I only want to do a good job in photographing the castle, but I am NOT interested in knowing anything about the castle's history, etc.) (This sentence is from the Oxford American Dictionary, 1980.)
(6) Some advice from The Columbia Guide to American English, 1993:
"Formal English often tends (sensibly) to omit it."
That is, when you write formal English (for example, a research paper, etc.) you should probably not use the term " as such."
(7) For further information, please go the search box at this website and type "as such." You will find many helpful threads (discussions).
