My pal Fred from ibiblio said he met Lennart Björneborn this week. I checked out his site and he's adapted Ranganathan's five principles of library science to the web world. Even though they are copyrighted [?], I'll include them here:

• Every link its surfer – ditto
  
• Save the time of the surfer – visualizing web clusters and small-world shortcuts
  
• The Web is a growing organism
