I have been studying categories, sheaf cohomology and complex analysis (the basics since I know just a little). Then recently I tried to find out more about algebraic analysis and these microlocal stuffs, but I couldn't find any introductory material.
I know about the books and papers by Kashiwara and they are a little advanced for me. (However, I have never seen Foundations of algebraic analysis since this book is not so easily found.) Any material, lecture notes, etc are welcome.
