new German references

[Brian MacWhinney]

Dear Info-CHILDES,
  Angelika Wittek has contributed a collection of 500 references on the
acquisition of German which have now been added to the CHILDES bibliography
which is on the web.  In collecting these references she received the help
of Gisela Lausberg and Daniela Neumann of the library at the Max-Planck in
Leipzig.  Many thanks to Angelika, Gisela and Daniela for this contribution.
These new references all have "German" in the Keyword field.
