@BuzzB: Unfortunately, a couple of the recent firmware versions had a bug in them with respect to syncing collections. After the upgrade to one of these firmware versions, the device does a fuller sync. The bug hit during this sync and cleared the collections on the device. A later sync restored the collections and what collections the purchased books are in. But, Kobo does not sync any details about sideloaded books. This means the collection details for sideloaded books was lost, and unless you have a backup of the database cannot be restored.

The bug has been fixed and released. I thought it had been before 4.3.8945, but I might have the wrong release. There have also been a few quick releases recently and I think a few people lost the collections in one release but didn't notice until after the next.

Whenever collections are mentioned, someone will recommend using calibre. We do this because it works and is fairly easy. Though, I'm probably not the person that should be saying that last bit. The links that meera gave are to good instructions. If there is something you don't understand or it doesn't work afterwards, ask and someone will help.
