Back in the day

when you
Back in the day needed
information

You got what you needed from a person,

You got what you needed from a person,
who knew where to find
the
documents
that had the
information
you needed.

Now

Now
you probably
use a
computer
to find the
documents
yourself.

The computer
scans a lot
of
documents
looking for
your
keywords.

And gives you a
list of documents
where your
keywords appear.

Sometimes,
the computer
searches
specific
subsets of
information
sources.

Sometimes, it searches everything it can.

The computer won’t know
what you mean, so it’s very
important to choose keywords
that are likely to retrieve the
documents you want.
