Calibre collection on Sony PRS-300

[Buz1030]

Hello all.

I'm new to eReaders, the Sony PRS-300 and Calibre, so please forgive my general ignorance. I hope this is the right forum.

I'm involved with schools in Guatemala. I'd like to create eReaders with COLLECTIONS, like "Illustrated Stories for 4th Grade", "Adventure", etc.

I have two books I'd like in my 4th Grade category. Each has a tag of "4th". But when I Send to Device, I see two folders in my device, each with author name as folder name. I want one folder called "Illustrated Stories for 4th Grade".

Calibre seems much more useful than Sony's Reader for PC, so I'd like to use it. I'm sure I'm making a simple mistake, but I don't see it. I've checked all docs and videos with no help.

If someone can direct me to a decent tutorial about collections, I and my Maya students will be most grateful!
