If you think that a question that was put on hold shouldn't have been put on hold,—if your reputation allows—vote to reopen it.
That said, my comment suggested revising the question so that some binds were included because I personally found the idea of compiling, evaluating, and summarizing all the ways a wizard could cast one or more extra spells per day overwhelming. (Also, I did not vote to put the question on hold; I thought that a still more industrious and adventuresome user than I might not find the prospect as overwhelming as I did!)
I admit that the list in the question is a good start, including as it does even one way—sin magic (né Thassilonian specialist)—that's included in the build in this answer that I'm pretty sure that the question (albeit obliquely) references.
However, I suspect that, while it's a good start, once even more archetypes are examined, spells like this one are included, templates that increase Intelligence scores are enumerated, original magic items are created in the answer using the printed guidelines, and everything else figured out that could possibly lead to the wizard casting just one more spell per day, the list will be much, much longer.
I would've kept my trap shut had the asker posed the question How can the build described in this answer cast more spells per day? or even phrased the question as a good optimization question, but, as it stands, I commented because, while I wanted to help the asker, when I was working out my possible answer in my head, I had no idea where to begin or—more importantly—where to stop.
