Wikipedia:ISBN

The Wikipedia software recognizes inline ISBNs; for example: ISBN 0-12-345678-9 becomes ISBN 0-12-345678-9 (the dashes are optional). This creates an external link to a special booksource page, with links to sites where one may search for the best price for the book or access information about the book such as reviews and reader reactions. It is important when making a link to not put a colon after "ISBN".

Some think that this is useful, as it allows readers to go to online stores and purchase books. However, ISBN numbers only identify a particular edition of a book, and the reader will not see the full range of versions of the book for sale. Please do not use ISBN numbers alone to identify books: add a proper citation as well as the ISBN. See Wikipedia:Manual of Style, Wikipedia:Cite your sources.
