The metadata database contains records for non-existent ebooks.
Exists: https://www.gutenberg.org/ebooks/1
Doesn't exist: https://www.gutenberg.org/ebooks/182
Example code:
from __future__ import print_function
from gutenberg.query import get_metadata
def get_all_metadata(etextno):
for feature_name in ['author', 'formaturi', 'language',
'rights', 'subject', 'title']:
print("{}\t{}\t{}".format(
etextno,
feature_name,
get_metadata(feature_name, etextno)))
print()
get_all_metadata(1) # US Declaration of Independence
get_all_metadata(182) # no such ebook
Actual output:
1 author frozenset([u'United States President (1801-1809)'])
1 formaturi frozenset([u'http://www.gutenberg.org/ebooks/1.txt.utf-8', u'http://www.gutenberg.org/ebooks/1.e

1 language frozenset([u'en'])
1 rights frozenset([u'Public domain in the USA.'])
1 subject frozenset([u'E201', u'United States. Declaration of Independence', u'United States -- History -- Revolut
ion, 1775-1783 -- Sources', u'JK'])

182 author frozenset([])
182 formaturi frozenset([])
182 language frozenset([u'en'])
182 rights frozenset([u'None'])
182 subject frozenset([])
182 title frozenset([])
Expected output:
I'd expect get_metadata("language", 182) and get_metadata("rights", 182) to both return frozenset([]) instead of frozenset([u'en']) and frozenset([u'None']).
Or better, as there's no such ebook, perhaps it should it return None or raise an exception: maybe IndexError or something custom like NoEbookIndex, or just don't add it to the database in the first place and let that raise whatever it would raise when an index is not found.
