Below is the first screen of results of a subject search on "gun
control." The search was input without applying any of the
limiters--to full text, to refereed publications, by date, or to
particular journals. In other words, everything that is in the
database shows up.
This search produced 3010 hits. A rule of thumb:
When the number exceeds thirty, it's advisable to "Narrow by
subdivision." This divides the results into smaller, more manageable
categories.
Note that two other subjects showed up because both contain the
words "gun" and "control."
Next we'll see the results of narrowing by subdivision.
