Currency refers to perceived validity of a rhetor’s knowledge claim to a particular discourse community/community of practice at a particular moment in time.

Currency is one of the five critical reading concerns proposed by Sarah Blakeslee (2004): Currency, Relevance, Authority, Accuracy, Purpose.

Scholarship is a conversation and ideas evolve over time. That’s why it’s so important to question whether the information you have is up to date. Thus, current research may reinforce or, alternatively, repudiate prior research. 

Readers–and this is especially true of teachers in school settings as well as clients in professional contexts–find it condescending and boring when the rhetor goes on at length about an idea that anyone who did a moment’s of preliminary research, even a 30 second Google search, had already discredited.
