MBA Reader started as an idea based on the concept that the leading business advice and knowledge is readily accessible and published in books. To acquire this knowledge and maintain a competitive advantage all you needed to do is read the books.
Simple.
So you can essentially get an MBA equivalent level of knowledge yourself, in your own time, following your own special interests.
This isn't quite enough and to enhance the delivery mechanism the information is highly summarised and presented in a fast easily digestable format.
An that's about it.
