ink.resenha.book.resolve

Every key Resenha's index knows for a book, and its other editions, from one key: a BookHive ID, an ISBN-13, an Amazon number or an Open Library work. Learned from BookHive's catalogue, readers' own links between their records in different apps, and Open Library. Public, no sign-in: any book app can fill the slots its records leave empty, such as Popfeed's hiveId or BookHive's ISBN. Answers come from the index alone; nothing is asked of any catalogue for them.
