We study the matter part of the algebra of open string fields using the 3-string vertex over the sliver state, which we call "comma vertex". By generalizing this comma vertex to the N-string overlap, we obtain a closed form of the Neumann coefficients in the N-string vertex and discuss its relation to the oscillator representation of wedge states.
