Do you find you ever want to read a random journal article or a sermon at random from your collection?
Restricting FSD's range to a subset would enable us to do this and therefore make our enjoyment of logos even better.
If you want to vote for it, go to http://logos.uservoice.com/forums/42823-logos-bible-software-4/suggestions/2494632-add-an-fsd-collection-book-option. It seems like a simple enough programming task so hopefully wouldn't need too many votes before it gets implemented. :)

Thank you. I had started another thread drawing people's attention to it as was very happy to see you'd done it for collections! If it's easy to do also for individual resources, it would be great as well e.g. I am strange in that I like to stretch my knowledge of apologetics/psychology by reading an article at random from Baker dictionary/encylopaedia, but regardless of whether that's easy to do or not, I would like to say I am already very appreciative! :)
