All the books are in good condition.
(i) Some books might be of use by students at high school and sixth form, college and university.

(ii) Parents wanting greater understanding of specific learning and communication difficulties (for instance, dyslexia or Asperger syndrome) may also find some of the books helpful.
(iii) As per parents, but also several books could be of use in teaching groups or tutoring individual students.
