The St. Martin's Sourcebook for Writing Tutors

The book is a collection of numerous extended tracts on various subjects, along with detailed advice for writing tutors. A lot of the advice revolves around being able to coach the students into learning for themselves, with a minimal amount of nudging from the tutor to ensure that the students are correctly assimilating the material. It also looks at [possible] cultural differences between having native English students and ESL students. The latter might sometimes expect broader advice about dealing with cultural differences in a majority English speaking community.
