This is a Drupal 7 module that will create nodes in a book archive based on ISBN's. ISBN's or International Standard Book Numbers are unique identifiers for books, and based on ISBN you can mostly gather quite a bit of information about a book as well as get a hold of its cover. The module will allow users to easily build archives of physical books based on these book's ISBN's.
This module adds a Fields API element that allows content creators to include IPv4 addresses with a node. It provides multiple input widgets to allow either host or network addresses (in CIDR notation) to be specified. It also provides multiple formatters to which will determine whether or not the CIDR mask is included in the display.
