/lit/ - Literature

Okay, so I might be a lazy ass for asking this. But, are there any particular sites that can give you a set of bulletin points you need to know before you read the book? I normally go through the Author's Wikipedia page to note down, who he was influenced by, the situation he lived in, what influenced him to write the book,etc. But it can be painstaking to seperate the necessary information from the useless info, also have to avoid the spoilers, and I end up missing some information time to time.
