Library resources are not always on their best behaviour during training sessions. They have been known to crash in the middle of being demonstrated, mysteriously change their interfaces between one session and the next, and sometimes turn up some rather unexpected results.
Xreferplus turned up a very odd result during training this week. This database includes a concept map option, a nice little feature where you can type in a word and get a diagram of related terminology, based on the dictionary and encyclopedia entries it contains. Once they'd been shown how it worked students had an opportunity to try it out for themselves. What I hadn't realised was that one of the reference books it contains is a dictionary of euphemisms. It seems that there is more to 'business' than is included on the syllabus!
