A primary source is written by someone who was there when it happened. If the author happened to participate or witness a Spanish mission, then it would be a primary source. Secondary sources are based off things that people learn from a primary source or a different secondary source.
No, a book written this year about life on a Spanish mission in Florida would not be considered a primary source, as it is a modern interpretation or analysis of historical events. Primary sources are original documents or artifacts that provide firsthand evidence of a specific time period or event.
