Listopia is the first option on the goodreads explore menu. It consists of user-created lists that anyone can vote on and add books to. Some are useful, but many are not. The older lists have way too many books on them and some people add their favorite books to almost every list. The better lists have carefully defined criteria and someone deleting the books that do not match the definition. The list creator and any librarian can delete books that do not belong on the list.
You can pick a list from one of the categories on the main page, or browse by tag, or search for a list. When you select a list, the top right of the screen will show the number of books you have read and the number that are on your to-read list, but it only looks at the top 100 books in the list. You can vote for up to 100 books on each list. If a book you want to vote for isn’t on the list, you can add it. You can rearrange the order of your votes and delete any, if you change your mind. You can like a list and comment on a list.
Anyone can create a new list. Pick a good title and try not to duplicate an existing list. Write a description and be specific on what books are eligible for the list. Don’t forget to add tags so people can find your list. You can add a maximum of 100 books to your list. Invite your friends to vote on your list and come back often to see who has voted on the list and what books they added.
The my lists link at the top will take you to all the lists you have voted on. Have fun with the lists and maybe you will find more books, but don’t expect the lists to be completely accurate.
