Old German gothic handwriting and print are very different from the Roman script most English-speaking genealogists use. For examples of old German Gothic handwriting see Old German Handwriting (Gothic) and the Handwriting Guide: German Gothic.
A useful chapter on German print and script is found on pages 204 to 217 of:
Schweitzer, George K. German Genealogical Research. Knoxville, Tennessee, USA: Schweitzer, 1992. (FHL book 973 D2sg.)
Another is on pages 171 to 197 of Smith's German Church Books. The chart in the next column shows how each letter of the alphabet looks in gothic handwriting and type.
An online class on is available called Reading German Handwritten Records on the FamilySearch.org website.
