Open Library for omniscient/omnischolar: an author's books, one record per edition - its ISBNs, publisher, date, cover - for the Merger to group the editions of each book; a book by ISBN or Open Library id; a search; an author's page. No key.

$openlibrary = (new OpenLibrarySourceFactory($http))->create(['mailto' => 'support@glitchr.io']);
$editions = $openlibrary->works('Monica Neagoy');         // every spelling of the name, every edition
$books = (new Merger())->merge($editions);                 // Planting the Seeds of Algebra PreK-2: one book, two editions
$openlibrary->work('9781452279701');
