Useful Links & Other Resources
Books are of course not the only source of knowledge. Even though I suggest spending less time reading daily newspapers, I still think you can occasionally come across a very useful piece on an industry or some problem (e.g. investing in an inflationary environment).
Also, many authors do not update their books, but speak regularly and share their more recent thoughts in interviews and podcasts.
A very important part of materials in this section comes from Warren Buffett and Charlie Munger who have one of the best and longest track records in investing, yet have not written their own books. You can still learn tons of useful points if you just read their letters and go through annual meetings of Berkshire and Daily Journal.
I try to keep track of all kind of useful materials in this category.
