BC
B.C. or BC (for "before Christ") is an abbreviation used to refer to a year before the beginning of the year count that starts with the supposed year of the birth of Christ.
Some people use ACN or BCE instead. See also AD and CE. For a discussion, see the entry on Anno Domini.
BC also refers to bookcrossing, which means releasing books from your shelf (where they will be of no use to anyone) into the world.
After registering the books on the internet and attaching a print-out bookplate with the registration number and some informations about B.C., the releaser may follow his books on their trip (and see, what others tink about them), if the finder reports his catch on the BC internet-site (see below).
More sophisticated forms of BC are bookrays and bookrings: a group of people "subscribes" to a book on the internet and the book is mailed from one participant on the list to the next (often across continents). Bookboxes function similarly; each participant (except the original sender) should however replace a specified number of books with volumes of his own(of the same genre).

B.C. or BC also refers to the province of British Columbia in Canada. [1] "B.C." is the traditional use, while "BC" is the more modern, being used as the official Canada Post code for mail, and in domain names such as vancouver.bc.ca. It is also part of the province's ISO 3166-2 code, CA-BC.
B.C. (sometimes BC) is also the name of a syndicated comic strip by Johnny Hart, which has run since 1958 and features wisecracking cavemen.
BC Powder is a name brand of pain reliever containing aspirin, caffeine, and salicylamide. [2]] "BC powder" can also refer to the light and fluffy snow which attracts skiers and snowboarders to the province (see above), or to the powdered chemicals in a fire extinguisher effective against burning liquids (B-rated) and gases (C-rated). These may also be known as "B.C. powder" (like "Utah powder", etc.), and "B/C powder", respectively.
