Librarians as GUARANTEER of continued free access to
  information. The gates don't stay open by themselves. There is a
  philosophy *behind* free access, one that has dominated the 'net
  but it's not necessarily a guarantee. Example: China. Something
  most of us never learn about Librarians: There is a creed. "The
  creed of a librarian: No politics, no religion, no morals" A
  very short book written years ago for librarians puts it
  plainly. That's the title. You don't need to read the book (13
  pages long) to understand its point. It is one of the guiding
  principles behind the REASON *why* the Internet today is free;
  why we have public forums where we can discuss things. No
  politics. No religion. No Morals. That allows the gates to stay
  open for freedom of information to continue, uninhibited; this
  very philosophy of the librarian. Librarians don't need to
  categorize or organize knowledge or control the flow; that's
  just a byproduct of having to make it easier when all we had
  were books and such. But the Internet does away with the Dewey
  Decimal System and Library of Congress subject headings; The
  internet is a better way. One day, perhaps libraries will
  disappear. Computers will successfully categorize and organize
  knowledge automatically, removing the need for human
  classification systems (beyond those set by the programmers).
  But somebody needs to have the right outlook to be sure it
  continues, lest a politician, or someone with a particular
  worldview decides that they have "a better way" for society. We
  don't normally think of a Librarian's attitude towards knowledge
  as Activism but they are Activists. A single politician trying
  to control future education who becomes popular is all it would
  take for access to free speech/thought/discussion/knowledge to
  end. Librarians have fought to keep controversial books on the
  shelves in children's libraries, only to have them removed by
  political forces of democracy / popularity.
