#TIL: "The book store supply chain [#Bookland] wanted to be able to identify individual books in greater detail than was possible with the U.P.C. code. […] The EAN aggreed and assigned them a country code [in 1985]. The code proposed by Bookland with a "978" prefix has now been accepted worldwide to identify #books and periodicals." #barcodes
