Here’s a list of resources that have informed my own approach to writing and editing. You may find them useful as well. I’ll continue to add to this list, so please don’t hesitate to send me recommendations!
Books
The Elements of Style (Strunk and White)
The classic handbook of written American English for over 100 years.
How to Write a Sentence and How to Read One (Fish)
This relatively little-known book has engaging, commonsense explanations of the logic of English grammar, and includes exercises for you to try on your own (although you need to read the text to find them). The first half of the book is especially useful for writers looking for help with grammar.
Writing for Social Scientists (Becker)
Excellent advice for writers in any discipline by one of the most influential American sociologists. Offers practical grammar and style lessons in an accessible and enjoyable format.
The Craft of Research (Booth et al.)
This standard book on the research process focuses on big-picture writing issues like building an effective argument.
Essays
Politics and the English Language (Orwell)
This essay is a “struggle against the abuse of language” that is especially pertinent to academic writing. It’s controversial, but short and worth reading.
Online resources
According to their own description, this is “a fun radio show and podcast about language examined through family, history, and culture.” Their most important insight is that many “rules” are inconsistent, controversial, and arbitrary.
The Writer’s Handbook (University of Wisconsin - Madison Writing Center)
An excellent resource on academic and professional writing, the writing process, style, grammar and punctuation, and proper citation.
Purdue OWL (Purdue Writing Lab)
A thorough repository of everything you need to know about academic and professional writing. They are especially known for their helpful style guides.
