Like many graduate students before trying to learn something about étale cohomology and Deligne's proof(s) of the Riemann hypothesis part of the Weil conjectures, I am hunting for references detailing basic sheaf-theoretic operations in the classical topology.

Here are some sources I found so far which discuss this, some of which by way of wise words of Bhargav Bhatt and Matt Emerton somewhere online.

- Freitag and Kiehl's book on étale cohomology and the Weil conjectures.
- Milne's book on étale cohomology.
- Kashiwara and Schapira's book on sheaves on manifolds.
- Borel's book on intersection cohomology.
- Last but not least, notes from Conrad's seminar on Deligne-Laumon. http://math.stanford.edu/~conrad/Weil2seminar/

But there's gotta be more! Specifically, I would appreciate pointers towards perhaps some sources penned by some more recent and younger "masters" -- although notes from Conrad's seminar pretty much fit this bill. But really, just suggest your favorite source that hasn't been listed yet, and perhaps give a reasoning what value it has over the ones I have listed already.
