isbn - ISBN lookup script

---------------------------------------------------

isbn is a simple Python script that queries the API provided by OpenLibrary
for book information when provided with a valid SBN, ISBN-10 or ISBN-13 number.

Keep in mind that this script is limited to the database provided by OpenLibrary
and thus there are possibly many entries that do not exist.

No API key is required as OpenLibrary provides the service free of charge, so
please be appreciative and do not spam this script.

Note: You will need Python 3 to run this. No additional libraries other than
the built-in json and urllib are required.
