Resources/guides for teachers : contains an annotated bibliography of sources that give practical advice to teachers and have materials that can be used in language classes such as ready to use activities and lesson plans. Most of them are well-known works published by major publishers so they should be fairly easy to find.
Resources/guides for students : is quite similar except it focuses on students. You might like to look at these when giving advice to students or refer students to them.
Professional organisations and groups : has a list of TESOL and language teaching organisations and groups. Many of these organisations run conferences, publish books and other material and report on current news and events in the field. You will probably find their websites useful and you might also like to consider joining one.
