Couldn't do this without your input!
Omit the glass on the sides, mostly due to cleaning and breakage concerns if moved. If there's already material there, work with it, not against it.
I mislead you with my "drawing". The "glass" and "screen" on the sides of the bookcase was referring to the front sliders. I thought about the light just on one side but I figured then it would get way to hot inside. Do you mean 2 lights on one side or one uvb basking bulb on one side? I'm thinking it will be kinda dim on the side without the light then. And maybe too cool?
You really think that 2" screen running across the front will be enough to keep it from overheating? What about the 12" depth? I was kinda worried about that. Do you know of anyone who uses a long tank that is slender like that?
Sorry for all the questions but you ARE the wiz!
The 12" depth isn't bad, but there's worse scenarios. Because the two bookshelves will be together, it may make up for a lack of depth. I'd feel comfortable with it. If your skink gets too big though, you may want to reconsider!
I do think the 2" gap on top is plenty of ventilation. I also worry about the screen door on the cooler side because, well, you're going to have a very large lizard with sharp little claws that are undoubtedly going to meet that screen, and I'd hate to see the result, even after a period of time. Plus, too much ventilation will not do your nose any good as I mentioned earlier, and drafts should be avoided.
I thought you were putting glass on the right and left sides of the case, 90' degrees from where the front of the setup would be. That's what I was suggesting against...
...as far as light, yep, keep the light all on one side, well, at least the useful light. The UV and the heat lamp should be on the same side. If you want a decorative light on the other side, the cool side, that's entirely up to you. There's really not going to be such a thing as "too cold," in your vivarium, since it will only get as cold as your house. Most people don't like their homes any cooler than about 60'F, which is cold by a lot of people's standards (how I like my home, for example...) so no worries about that.
