New bookcase (Update)
The missus gave me an ultimatum since we had books crawling all over the living room because my room’s bookcases are all full. I checked prices online for real book cases made out of wood and not particle board and I almost had a heart attack when they were asking +$200 as starting price.

Six feet tall, six 3-foot by 12″ long shelves and I reckon I can get creative and put more books on top. On average, every shelf is capable of taking on 32 paperbacks, so if I shove real hard, I can manage to squeeze 200 books in there. But it is sized vertically to take the average hardcover with an inch to spare on top.
Tools I already had so it was just wood and screws for a total of just under $90. OK, add $10, I just remembered I bought stain too to match the “decor.” (Nope, the $90 includes the stain, I just checked the list)
And the best part? The missus approves!
PS:
Just to show the bookcase under load. This is the first one I made years ago doing service in my room right now.
Bottom shelf has two boxes of lead ingots on the left and shotgun shells on the right. The shelf above is just bullets on the left and mostly primer everywhere else. Above that is books and assorted little stuff I can’t find a palce to put.
