"Surface" has a Library/Dewey Decimal mention

"Surface" is an interesting Sci Fi show about a sea creatures (not sure exactly where they come from yet...) but I had to mention a use of a Library and Dewey Decimal System.

Seems like the Dewey Decimal Number makes for a good encrypted secret message that leads to the location of forged documents and a Treo 700w (I think that's the model[damn I am a gadget geek]). I was surprised that the Scientist character recognized that DDC right away considering the Library Congress Classification Numbers are more common in Research Libraries. I guess Dewey Decimal is more recognizable for a library classifcation system.
