 (However, as noted in Section~\ref{sec:classical_electrostatics} these cut-offs are not normally applied to electrostatic interactions because truncating these interactions induces worse artifacts than does including interactions with multiple copies of the same particle. 
 Instead, what are often termed ``cut-offs'' that are applied to electrostatics are instead a shift from short-range to long-range treatments.)
 Such cut-offs impose a natural lower limit to the size of a periodic simulation box, as the box must be large enough to capture all of the most significant non-bonded interactions.
-Further information on periodic boundary conditions and discussion of appropriate cut-offs may be found in \citet{LeachBook}, sections 6.5 and 6.7 and \citet{ShellNotes}, lecture on Simulations of bulk phases.

 %DLM: I have permission to migrate Shell's notes to GitHub, specifically to https://github.com/kofkeLab/Mol-Sim-Intro, so I should go ahead and prioritizing these particular notes there and then cite here.
 
 It is very important to note that periodic boundary conditions are simply an approximation to bulk behavior.
