It's not fair that only the Dragonborn gets a mod that makes his unread books glow. The Nerevarine is far more attractive AND bathes far more regularly than that lizard yeller. 
Thanks to the magic of MWSE-Lua, such a thing is now possible.

FEATURES

Unread books now glow with the same sheen that enchanted weapons and armor do, as they make use of the same effect. This also means that it'll work with any replacers that replace those effects.
Furthermore, different kinds of books will glow different colors. Skill books and scripted books glow red and green, respectively, while normal books glow a bluish-ish color.
Obviously, this requires MWSE-Lua.

INSTALLATION

Install this to your data files folder so that it overrides it. The mod will, due to some limitations, not work on the first cell you load into the very first time, but will work in every cell after that.

CAVEATS

As noted, the first time you load into a cell, there will be no glowy effects. Simply enter a new cell and it'll activate.
Second, there are occasions where a cell loads and the glowy effects don't apply. I don't know why, Lua and I are mortal enemies due to a falling out in college.
Because this works off enchantment effect textures, replacers that eliminate those won't work with this. Probably.
