**Some reading:**

- For a careful treatment of compactly generated weak Hausdorff spaces, you may wish to look at Neil Strickland's notes.
- For a very systematic treatment of cofibrations and fibrations, consider Hirschhorn.
- For a proof of the local nature of fibrations, see [May, Section 7.4].
- For a nice treatment of principal bundles from the simplicial point of view, consider [Goerss-Jardine, Sections V.3 and V.4].
- For the construction of the spectral sequence of a filtered complex, see for example [Weibel, Sections 5.4 and 5.5].
