 ## Metadata
 
 The book texts are accompanied by basic metadata fields such as title, author and publication year (see [Data Fields](#data-fields) below), as well as IA and OL identifiers. The metadata can be expanded to include more information about e.g. subjects, authors or the files, by using the [OL Books API](https://openlibrary.org/dev/docs/api/books) or [OL Bulk Data Dumps](https://openlibrary.org/developers/dumps) and the [IA Metadata API](https://archive.org/developers/md-read.html).
