If you are curious how to get it here are the instructions:
- I created a shelf called "2012 - Reads" at the beginning of the year to organize my books by reading year. Each time I read a book in 2012, I just included that tag.
- Go to your profile on Goodreads and select to "Edit".
- Select the folder "Widgets" from the top.
- Scroll down to the Grid Widget section and change the drop down menu option from "Read" to "2012 - Reads"
- Copy and paste widget Java script to your place of choice.
