isbn-groups

mapping ISBN group prefixes with ISO 639-1 language codes (2 letters code), when that's possible, that is a strong assumption that a book published in that country would be in that language

Installation

$ npm install isbn-groups

Usage

Example using isbn-groups and isbn3 for ISBN parsing

const { parse } = require('isbn3')
const isbnGroups = require('isbn-groups')
  • example 1
const isbn = '9782707301529'
const { prefix, group } = parse(isbn)
// prefix: '978'
// group: '2'

isbnGroups[prefix][group]
// => 'fr'
  • example 2
const isbn = '9789953211206'
const { prefix, group } = parse(isbn)
// prefix: '978'
// group: '9953'

isbnGroups[prefix][group]
// => 'ar'
