9780306406157

9780306406157 is an international standard book number (ISBN) in its 13-digit form, used to uniquely identify a specific edition of a book in the global publishing industry. The number conforms to the ISBN-13 standard, which uses a prefix, group, publisher, title, and a check digit.

The composition of 9780306406157 breaks down as follows: prefix element 978 indicates the EAN/UCC-encoded book industry code; registration group 0 denotes English-speaking regions; registrant element 306 identifies a particular publisher; publication element 40615 specifies the edition; and the final digit 7 is the check digit used to validate the number under the modulo 10 calculation with alternating weights of 1 and 3 across the first 12 digits.

The ISBN-13 system was introduced in 2007 to harmonize book numbering with the international barcode system; it often corresponds to a specific edition and format (hardcover, paperback, e-book). The 978 prefix allows for future expansion and compatibility with existing 10-digit ISBNs; older 10-digit ISBNs can sometimes be converted to 13 digits by prefixing with 978 and adjusting the check digit.
