Book Smelling

So now smelling books and keeping track of what they smell like is art. (The New York Magazine goes into more detail.)

I would like to propose that is not art but rather a hobby. See, it's funny if you consider it a hobby, but it's just annoying if you consider it art.

I was amused by one of the comments on the LISNews post:

this is completely unscientific. she omits all types of metadata that a librarian would include.
how long did she sniff each book?
did she sniff a random page or the inside cover or page 23? and "paper-y" in place of "paper"??? is that like saying a book has "around 200 pages"?

How would you even decide which page to sniff in a scientific manner? Page 23? Halfway through the book plus one page?
