Self-studying

Hello,

Having myself no formal education in literature or the arts in general, I embarked two years ago in a self imposed journey to read the classics of world literature. Now having read in the vicinity of perhaps 300 works, I am longing to deepen my understanding of those works and literature in general as I keep going with my reading.

Is there a specific source for study material you would recommend? I have developed some insights of my own and have preferences in the works I’ve read so far, but it would be interesting to read scholarly or expert studies of those works, why they are considered classics, where their value lies, how they fit in the whole corpus of literature, etc.

Thank you!
