This is a downside of Libgen: duplicate uploads, missing or erroneous metadata. You start wishing that there was at least some curation of the collection, so it could approach the quality of an academic library catalogue as many users are usedto. But I guess the people behind Libgen want to keep the number of people with database edit rights small. (When you upload a book, you yourself can edit the metadata for that book for 24 hours, but you cannot go through the rest of LibGen's database and make corrections.)

Maybe they should consider a system where users can suggest tags/metadata or flag erroneous data that can be reviewed and allowed by a select few?

Integration with BookBrainz would be nice. The Brainz projects already consist of massive amounts of metadata curation and it would be possible to transfer that knowledge a bit.
