The given expression is:

\[
\lim_{{x \to 3}} \frac{1}{{x - 3}}
\]

Now, let's analyze the limit as \( x \) approaches 3.

### Step-by-Step Solution:
- The denominator becomes \( x - 3 \).
- As \( x \to 3 \), the expression becomes \( \frac{1}{0} \), which is undefined.
- This implies the function approaches infinity or negative infinity depending on the direction from which \( x \) approaches 3.

#### Directional limits:
1. **From the left** (\( x \to 3^- \)):
   - If \( x \to 3 \) from the left (values slightly less than 3), \( x - 3 \) will be negative.
   - Therefore, \( \frac{1}{{x - 3}} \) tends towards \( -\infty \).
  
2. **From the right** (\( x \to 3^+ \)):
   - If \( x \to 3 \) from the right (values slightly greater than 3), \( x - 3 \) will be positive.
   - Therefore, \( \frac{1}{{x - 3}} \) tends towards \( +\infty \).

### Conclusion:
The limit does not exist in the conventional sense, but we can say:

\[
\lim_{{x \to 3^-}} \frac{1}{{x - 3}} = -\infty
\]
\[
\lim_{{x \to 3^+}} \frac{1}{{x - 3}} = +\infty
\]
