Bookclub - a module for storing information about books

Attributes:

common:

• title
• authors
• description
• series
• [images]

subjective: (- user (implied))

• rating
• rating type (- read (datetime))
• review
• shelve
• categories/genres

If we seperate common from user attributes, we can just merge common into a global object. User related (subjective) should infer the user from who posted it and merge into a list.
