Substack vs. Library Stack

I imagine you'll get a lot of responses to this, but one reason to use a
library is its code is available to all open stacks in LC: functions,
commands, etc.  Sort of like having a backscript for all open stacks,
instead of just one.  A substack doesn't do this.

Another frame of reference that might help is the difference between
behaviors and libraries: code in behaviors is object-specific, available
only to those objects that have the behavior assigned to them, while code
in libraries is universal, available to all objects anywhere, and doesn't
require any assignment.

Other people will probably chime in with additional insights.
