These are 9 books, some explaining the practice of drawing in different media and some books on the use of pastels and acrylic.
I feel this is a very good starter pack of books for a student or for anyone reading about art as a hobby. 
For a practising artist these represent books that are easy reference or inspiration, with two books adding food for thought with historical references. 
All books are very good and look like you've chosen them in the book shop, however there is a pencilled price at the front of the Jenny Rodwell book.
The cost of postage is due to the weight of the books.
