Hi, did you ever get the books you were looking for? Local books for primary/high school/college/university/postgraduate level are yet to be availed online- but if you'd like someone to walk into a good bookshop for you and then ship the book(s), then let me know so as to make arrangements. Amazon.com has options, too, but I'd rather you work with what has been approved for the local education system for it is of highest quality.
