What are good books or websites to learn academic writing?

There are good Online free courses available, and you can get certificate if you are willing to pay some fees... These are MOOC courses. I am trying them with same intention of improving English. This suits me well, as I am also non-native speaker of English. These online courses are great way to start/grow as there is structure and you can work at your convenience and pace. Pickup project/activities that suits your needs. Most importantly there is lot of advice/suggestion and practice for improvement. Surely worth trying if you are serious at improving Academic writing. Here are some Links: 1) Great for Beginners in academic writing. https://www.coursera.org/course/basicwriting 2) This is good for variety of ways to practice academic writing, understanding review and editing process. https://www.coursera.org/course/composition 3) There are few more, but I haven't yet tried them. But please explore.. https://www.coursera.org/course/composition https://www.coursera.org/course/sciwrite I guess there are few more available on EdX - but I haven't tried them. Please do post, if you have additional sources.

OK, obvious plug! But feel free to read my textbook or watch my instructional videos (all free) that I assign my students: http://keneckert.com/engkorea/writing/index.html.

I don't know any informative book that can help you in academic writing, but I would recommend you to go through different websites or blogs. This is the Blog (https://writersperhour.com/blog) I used, It's quite educational. They have an awesome collection of articles that explain the best ways to write various academic papers. The best thing from their blog is that you can use the information they provide not only for you academical goals but for developing your writing skills as an academic writer. Also, I would like to recommend you checking Samples and Examples of others works. You can catch the main ideas and hooks used by professional writers. Here is a link for an excellent collection of free custom paper samples.Footnoteshttps://plus.google.com/b/100493970763546237946/collection/4wYo9
