[R] Minimizing both AIC and df in model selection

Dear R users,

Suppose I have a set of 10 candidate models, and these all differ by a delta-AIC of 5.

Would it be sensible, then, to choose the best-fit model as the one that has *both* minimal AIC 
*and* minimal number of d.f.?

Are there any references for such an approach?

Many thanks for your help!

Best wishes,
