This is my favourite book on the topic of scientific writing. Although I am primarily a social scientist these days, and there is some variation in how we write as compared to the biophysical sciences, I have found this book immensely helpful as a reference throughout my PhD. Every time I am feeling stuck with a section or don't know where to begin, I pick up this book and almost invariably find the answer. I like that the book has succinct, clear writing (otherwise I probably wouldn't trust its advice). But I also like that it mixes humour and narrative into the advice, making it surprisingly entertaining to read. I have used previous editions of the book, but I find the 6th edition or later are the most useful given how much the publication process has changed. The writing advice in earlier editions is still solid, but the latter stages of publication have changed a bit since the early editions of the book. In addition to covering the writing, reviewing and publication of scientific papers, this book also covers other writings, conference papers & posters, theses, CVs, grant proposals, recommendation letter, and how to actual do peer review yourself. Overall, a comprehensive, well-written, useful and interesting book on the subject.
