Hello, I am new here and had already posted this (probably in error) in the Sony PRS-700 forum, but I can confirm that on that device, it seems to be sorting one of my collections (I have only tested two) in an arbitrary order, and not via the "Book 1, Book 2" series designation as set up in Calibre.
I asked in the other thread, but: is it an incorrect assumption that the Sony Reader *should* be looking at the numbering of Calibre's Series field/numbering for that sort?
I also cannot figure out how it's sorting--it's not alpha, it's not anything else that would be in the meta information. I have a different collection that appears to sort correctly, but it's only got a few books and I may have actually put them into calibre in order.
Any input appreciated. This isn't a big thing, just one of those nagging bits that you'd like to see working correctly. Calibre is very much appreciated by this Mac user.
EDIT: Another hint--I just realized that it's sorting in the same order as if I switch it to By Author (which is the same for the whole series). So it's falling back to whatever field gets sorted after Author (or something), which still has no easily recognizable pattern. This doesn't seem to correlate to 'Date' for me, either.
