For those readers who are not librarians or who do not have a second address that is also coincidentally the address of a public, college or company library you might not realize just how books come to be selected for your library. Some are slected because you, the user of the library has requested that the book be placed in the library, some are selected because they have local interest, and are therefore germain to the collection of that library. Others are germain to a specialty of a library, such as graphic novels, travel books or other genres. Some, however come with the recommendation of powerful industry journals such as Library Journal, Kirkus Reviews or Booklist. Slate.com has an interesting article about this topic.
