Graduate level texts/notes that cover the Short Run and Long Run Costs of firms' production In undergrad econ we learned that it would cost a firm more money to increase its production in short term than in long term. 

MWG does not seem to cover this topic. I need a Graduate level texts/notes/papers that cover the Short Run and Long Run Costs of firms' production (or supply curve).
Textbooks:


Mas-Colell, Whinston, and Green (1995). Microeconomic Theory. Chapter 5
Geoffrey Reny. Advanced Microeconomic Theory, 3rd edition. Chapter 3
Kreps (1990). A Course in Microeconomic Theory. Chapter 7
Varian (1992). Microeconomic Analysis, 3rd edition. Chapter 5


Lecture notes: I think undergraduate notes are more useful on this respect. For instance:


Chapter 6 to Chapter 8 here.
Set 6 and 7 here (go to downloads to get slides).


In my experience, graduate notes deal with deeper issues. For instance this, this, or this one dig much deeper, skipping SR/LR cost functions altogether.

In any case, here Google is your friend. The trick (imo) is to add "pdf" to the search, to get lecture slides. For example:
