Gee, when I was a boy (and did that stuff for a living),
we used to head to the bookshelf, pull out the mechanical
data sheet, and make our own footprints. If it's something
interesting you draw it from scratch. In this case, take a
bigger or smaller version of the same package and modify
it.
Using standard library parts without first consulting your
soldering/assembly contractor is pretty much asking for
trouble with SMD anyway. Library parts are never quite
right, doubly so with SMD.

Re: Protel 16pin TSSOP foot print

Manufacturer's standard footprint (ie: duplicate the layout from
the spec sheet) would be as best as most soldering/assembly orgs
could hope for. What would not be good is to take the software
mob's 'standard' footprint. When you consider that some of those
libraries are built by putting the work experience kid in a dark
room and encouraging him to build as many variations on any given
theme as he can without regard for mechanical properties of molten
solder, cooling solder, etc, then those footprints may turn out to
be, shall we say, less than optimal.

You could always look here:

but you will still have to define the pattern for your PCB programme.
