Could you expand on the parallel between librarianship and say, being
a medical doctor? For example, the similarities in the expectations
of users that you're seeing or in the sanctions that are applied to
librarians when they fail to find the right resource for a user's
needs? I'm not sure library users see librarians in quite the same
way as they see their lawyer or doctor.

The google code of conduct is at: http://investor.google.com/
conduct.html and makes interesting reading...

It contains a section on serving their users well, taking a stand on
issues that affect their users, respecting each other at work and not
letting personal issues become a conflict of interest; all in all it
seems to me to be very similar.

and yet google have one - for all the world to see and discuss and

Not knowing much about Dostoyevsky I figured I'd try http://
www.google.co.uk/search?q=Dostoyevsky and see what I got. The very
first hit is the wikipedia article which contains the common
transliterations of his name as well as the russian. More
interestingly many of the first page results were for sites using the
spelling 'Dostoevsky' as their prominent form. But as I'm not an
expert on any russian authors I can't say what I'm missing out on.

The term "relevance" simply means "it meets my needs". Something that
the world at large believe Google does very well. Certainly the
search discussed above looks to me like it would meet the needs of
all but the most ardent researcher - and I would expect they would be
using far more distinct terms than 'Dostoyevsky'.

That is to say, relevance is about matching the result to the context
of the user. What Google excels at it is guessing that context from
what you've typed, how much you've typed, how specific it is and
much, much more.

Surely a next-generation catalogue has to do a better job of that?
