A simple Calibre metadata source plugin that uses the getMetadata service from http://xisbn.worldcat.org
- Searching is by ISBN only
- The returned metadata is limited to book title, authors, publisher, language and year (not the precise date)
- Other xISBN services like
getEditions
or searching the whole worldcat database are not supported - The free publicly-accessible version of xISBN is limited to 1000 requests per day and the plugin does not have support for the subscription authentication
