-=== Configuration

-Configuration is optional. The available option is `logger` which is a `Logger` instance. By default, the logger is `Logger.new($stderr)` with `Logger::WARN` level. To change the logger level, use `RelatonIsbn.configure` block.
+To retrieve bibliographic items, use `RelatonIsbn::OpenLibrary.get` method with ISBN-10 or ISBN-13 as an argument. Allowed prefixes are `ISBN`, `isbn:`. Prefix and hyphens are optional. The method returns `RelatonBib::BibliographicItem` object.
