Books

Accessibility to reference material is literally at our finger tips and readily available if you know where to find it.  I am what you would call a little "old school" and still very much enjoy having physical reference material in the form of books. Something that I can physically hold and touch and doesn't rely of wifi or the internet to access :)  The lil oil spot has some wonderful reference material that I would encourage all oily folk to have in their possession. For ease of use and to have something that you can refer back to over and over and over again. Whether you are a beginner or a seasoned oiler there is something for everyone.
