The musings of Charlie Munger (Warren Buffett’s, newly-late at 100 years old, partner at Berkshire Hathaway) are available for free at Poor Charlie’s Almanack: The Essential Wit and Wisdom of Charles T. Munger
While there is some repetition between chapters (as these are based on talks he gave), there is much to be learned by many here. In my case, much of it gave confirmation to my thought processes and business policy, so I’ll take this as a pat on the shoulder 
I ended up copying each chapter of the book the book sequentially to a single “Word” document so I could easily read off-line.
Another useful learning resource for investors is to read (again, sequentially - accompanied by a graph of macro and market results over the years to give context for specific comments), are Warren Buffett’s letters to stockholders (available here: https://www.berkshirehathaway.com/letters/letters.html).
