_Germans to America_ is a book series devoted to indexed
     transcriptions of passenger lists of vessels carrying Germans to
     America.  It will cover the period 1840-1897.  It does not index
     all Germans who emigrated to America, and it does have problems
     with its inclusion criteria and transcription fidelity.  But it
     is very easy to use and often quite helpful.  It should be
     considered to be just an index; you should always consult the
     source passenger lists for entries of interest, as they may
     contain more information and the index may have errors in its
     transcription of the source information.  Note also that 000
     means either Obermoellrich or (usually) an unknown place!

     The volumes that have appeared so far are listed on the German
     genealogy server at
       <http://www.genealogy.net/misc/emig/GermansToAmerica.html>
     The books themselves are not on the Internet, but they are
     available at many large research and genealogical libraries.
     A list of holding libraries is available on the same server.
     A portion of the series is also available on CD-ROM.
