The Web is awash with advice on academic writing. Here is a sampling of excellent resources that are likely to fit your needs as a student:

• Comprehensive: Purdue University in Indiana has a large and inclusive set of high-quality online handouts. It gives advice on writing in specific genres (including a section on writing application letters and résumés), and it's especially reliable on matters of referencing, style, and grammar.
• Writing in the Disciplines: Thompson Rivers University in British Columbia (formerly University College of the Cariboo) has created a lively set of pages about the specific functions and methods of writing in the Humanities, Social Sciences, Sciences, and Business. Read what profs and students say about how and why they write; get advice and see examples from each subject area.
• Literary Writing: The University of Victoria offers an attractively-designed set of advisory files, called Hypertext Writer's Guide. It gives firm advice and good examples, mainly on writing about literature.
• Scientific Writing: Don't miss the fine website of the U of T Engineering Communication Centre. Have fun with the Interactive Tutorials, including an online bibliography-builder, and visit the Online Handbook to see what makes good lab reports, abstracts, memos, web documents, and other scientific and practical forms.
• Style: Jack Lynch, now an Assistant Professor of English at Rutgers University in New Jersey, did his doctoral research at the University of Pennsylvania on the eighteenth-century dictionary-writer Samuel Johnson, noted for his witty and succinct definitions. Lynch's Grammar and Style Notes show some of the same qualities.
• Grammar Review: Hypergrammar is the online textbook of a grammar-review course at the University of Ottawa. You can give yourself a thorough review of the parts of speech and the standard rules of sentence correctness—even spelling rules. Then take the review tests and check the explanations. The sections on word choice, paragraphing and organization give advice on what's suitable for academic writing.
• English as a Second Language: My pick in this category is a listing of Interactive Language Exercises on the Internet TESL Journal website. Have fun with the well-constructed games and exercises for reviewing points of English grammar and usage. (Also consult our selective list of other ESL links.)
• Punctuation: If you think science and writing don't mix, have a look at what NASA (the US National Space and Aeronautical Administration) has to say about grammar, punctuation and capitalization.
