Relationship in View
Although your question seems a bit less detailed than it should be, I assume that you need some way to connect a node type (article) to another node type (book). For this you can use References module or Entity References will be even better.

You can add an entity reference field to book content type. Then, when you create a book, you can select relevant articles. If you want to have two-way relationship (book &lt;--> article) then you can also use this module: drupal.org/project/cer
A good addition can be this module also: http://drupal.org/project/inline_entity_form which allows you to create or select your articles when you create a book.

Then in your view, you can show book's titles as fields.
Add a relationship with your entity refrence field.
Add a field "title" but select relationship you just added.
Group the results by first field (title only)
