Where do you go if you want to read about a book? Sparknotes is an ok read, but kinda rudimentary and lacking any serious opinions or insights. There has to be something more on this big internet.
For example, I just finished War and Peace and I feel I could read a whole other book just talking about it.
The only right answer in my opinion is to ask to a competent relative. In addition to my family, I've drawn quite a lot of relevant relations in my life, so I simply ask them their opinion on a book. My main sources are my favorite book seller, a librarian I've befriended over the years and my partner. It's really uncommon to not have a feedback on a title I'm looking for.
a lot of times if you have a specific search / question you'll get a Google Book preview result that you can read.
if you want more then type the title of this book into libgen and download it
if you're in uni still, look at JSTOR
or go to a uni library. at most uni libraries there tend to be more books about an author and his/her works than copies of his/her works. at mine, there's a small section for Joyce's novels, and the entire rest of the shelf is biographies and literary criticism
This is a bad idea. /lit/ is a collection of anonyms you can't decently trust, especially when it's about having read a book. The stronger you relation with the people grow, the more you know about them, the fairness of their judgment, their honesty, the quality of their tastes, the more you can blindly believe and follow the advices they provide. The more similar concept I can think of here on /lit/ are the “tripfags” but you'll have to read them for years before having a fair opinion. Anyway, they could still lie. We don't speak enough here to clear beyond doubt any hollow message.
