Models for Book
|
|
|
|
Series -> Work -> Edition
|
|
|
|
Series is not fully implemented at the moment
|
|
|
|
Goodreads
|
|
Famous works have many editions
|
|
|
|
Google Books:
|
|
only has Edition level ("volume") data
|
|
|
|
Douban:
|
|
old editions has only CUBN(Chinese Unified Book Number)
|
|
work data seems asymmetric (a book links to a work, but may not listed in that work as one of its editions)
