Macguba is correct they are in the stringtable.csv, however the stringtable is in the BIN folder and can be displayed with Notepad or Wordpad.
Look for entries beginning with:
STR_QUOTE_XX
and
STR_AUTHOR_XX
........where XX represents a number between 1 and 42 also STR_QUOTE_LAST and STR_AUTHOR_LAST.
