Some 50% of my scanned books have empty cover. This can be easily fixed in CLZ Books Web, by searching for the cover online I’m finfig out. I’m assuming the cover is only automatically added when found in central database? Wouldn’t it be worth considering to ad covers automatically based on online sources? Users could correct a false match, but it seems to me the match is ok most of the time.
Our Core book database has all kinds of ways it automatically scours the web/gets images for books. You can always tap/hold a book in your mobile app and hit Update from Core, if a cover is available for one you didn’t get one when adding it, it will download it then.
“Find Cover online” is indeed a feature from CLZ Books Web only right now!
