An Introduction to the Thought of S.R. Ranganathan for Information Architects (Boxes and Arrows) -- "S.R. Ranganathan was the greatest librarian of the 20th Century. No one else even comes close. His ideas influenced every aspect of library science (a term he is credited with coining), and because he was such a complete and systematic thinker, he was gifted in the development of all areas of the field, including theory, practice, and management." (Comments: This was my first exposure to Ranganathan.)
