Recently, I created a detailed outline of my thesis. Looking for ideas about how to structure it best, and for stylistic advice, I went through the excellent advice collection by Tao and Yuan Xie. The following links have proven to be very helpful:
- Writing Tips is a short list of five important hints
- Common Bugs in Writing is a longer, detailed list of stylistic advice and LaTeX hints
- How to Write Up a Ph.D. Dissertation is very good advice on structuring, keeping focus, plus some typography
- How to Organize your Thesis is a great document about, well, just that.
