American Library Association's Digital Reference Guidelines
The definition formulated by the American Library Association's (ALA) 2004 MARS Digital Reference Guidelines Ad Hoc Committee contains three components:
- "Virtual reference is reference service initiated electronically, often in real-time, where patrons employ computers or other Internet technology to communicate with reference staff, without being physically present. Communication channels used frequently in virtual reference include chat, videoconferencing, Voice over IP, co-browsing, e-mail, and instant messaging.
- While online sources are often utilized in provision of virtual reference, use of electronic sources in seeking answers is not of itself virtual reference.
- Virtual reference queries are sometimes followed-up with telephone, fax, in-person and regular mail interactions, even though these modes of communication are not considered virtual."
In January 2011 QuestionPoint and the American Library Association were in talks about offering a National Ask A Librarian service across the whole United States of America. At present the Ask services in the US are run at a local level.

Famous quotes containing the words american, library, association and/or reference:
“[If] Playboy’s Hugh Hefner has done nothing else for American culture, he has given it two of the great lies of the twentieth century: “I buy it for the fiction” and “I buy it for the interview.””
—Nora Ephron (b. 1941)
“A man’s library is a sort of harem.”
—Ralph Waldo Emerson (1803–1882)
“It is not merely the likeness which is precious ... but the association and the sense of nearness involved in the thing ... the fact of the very shadow of the person lying there fixed forever! It is the very sanctification of portraits I think—and it is not at all monstrous in me to say ... that I would rather have such a memorial of one I dearly loved, than the noblest Artist’s work ever produced.”
—Elizabeth Barrett Browning (1806–1861)
“I think, for the rest of my life, I shall refrain from looking up things. It is the most ravenous time-snatcher I know. You pull one book from the shelf, which carries a hint or a reference that sends you posthaste to another book, and that to successive others. It is incredible, the number of books you hopefully open and disappointedly close, only to take down another with the same result.”
—Carolyn Wells (1862–1942)
