go-isbn

Feature Overview

• Retrieves book details using ISBN10 / ISBN13 from 4 providers:
  • Google Books
  • Open Library
  • Goodreads (requires env var GOODREAD_APIKEY to be set) free
  • ISBNDB (requires env var ISBNDB_APIKEY to be set) 7-day trial
• Validates if a string is in valid ISBN10 / ISBN13 format

go-isbn will spawn equal number of go routines each querying a single provider with a max timeout of 3 seconds. First valid result will then be returned. Will return book not found only if all providers fail. Will default to all available providers if none is specified
