The cross-reference notation of UF, BT, RT, SA, and NT has to be explained; the importance of choosing the most specific heading available, rather than a general term, must also be emphasized. There are four ways to find the most specific LCSH terms for a particular topic; two of them come from using the red books, two from using the online catalog itself. All four ways are important; none is obvious. Each must be taught
