I just got a new Paperwhite and have been trying to decide what route I'm going to go with ebooks; do I just use Amazon, do I buy from other sources and convert as necessary, etc. To that end, I've been experimenting to figure out what library organization I like. The new series grouping is really nice and I like the way that works. However, I'm having trouble figuring out how to utilize it.

Books I sideload (from other sources) do not group into series for some reason. I've been trying to figure out what criteria Amazon uses. The Series and number fields in the metadata do not seem to factor in. But also setting up the ASIN (which allows the kindle to link the item to the store, downloads the Amazon book cover, etc), also does not group by series. However, getting the same books from Amazon directly does group them by series. If I take those same books from Amazon, download them, convert to a different format/update meta data in Calibre do group correctly into series. It doesn't seem to be purely based on Amazon cloud data, or by meta data.

I'm trying to figure out if there's a way to get side loaded books I purchase from places besides Amazon to group into series. If anyone has any ideas on this it would be appreciated
