I agree. This felt very rushed.

It's explained how to get detail information about any item selected. The items have been listed from media table using full_catalog_array() function, but now there has to be created another function single_item_array($id). $id variable points the item to be selected. Inside that single_item_array function, queried database that joins three tables to get information needed about the item(or book) and save them in $results variable. $results fetched and saved as $catalog and returned as the function output. It's array and is shown with var_dump function in the browser to know what details about the item you have got.
