Searching
Records and fields
.Records: the building blocks
of databases, records describe information sources.
It is unrealistic, at this time, to expect all
information sources to come directly to a computer
screen on demand. The reasons for this will be
clearer to you as you become more experienced
finding and using information. In the meantime,
having a record describing a source that you can
then find using your own abilities and knowledge
is an excellent starting point. The description
in a record uses elements called metadata
[information about information]. In many
cases, the text itself will have to be located
using other finding tools. Some libraries provide
links to the text of articles, when available,
at their own expense.
Fields: the building blocks of
records; these are the sections of a record where
information is stored.
For example, your driver's license or ID card
is a record about you with fields describing
your name, eye color, height, address, and so
on. Field names can vary, but in library databases
author, title, subject, publisher, and publication
date are common.
