The formula for permutation is $nPr = \frac{n!}{(n-r)!}$, where $n$ is the total number of items and $r$ is the number of items being selected. 
In this case, $n=8$ (since there are 8 available items) and $r=5$ (since we're selecting 5 items). 
Therefore, ${ } _{8}P_{5} = \frac{8!}{(8-5)!} = \frac{8!}{3!}=\boxed{6720}$
