I know it isn't brand new, but recently one of the icons in the concordance tool is a gem icon. I am used to seeing the cover of books I own, and I am used to seeing the block/lego-looking icon of books I don’t own but can preview. But, I cannot figure out the new gem icon. The resources all seem to link to items I can open from my library (like those with a book cover image), so what is the difference between a resource listed with a book cover and those listed with a gem?
Thanks
