Are requests for analyses, interpretations, restricted to single sources (eg McCawley, CGEL) acceptable on ELU?
Most of McCawley, and all of Huddleston and Pullum, for instance, are not available to the majority of contributors. But a bigger problem I have with such questions (eg How is 'compound noun' defined in CGEL) is that they focus attention on one treatment, which, whether the treatment is optimal or not, seems unscholarly to me.
Two of the three answers given to the cited question at this time can be seen to be strictly non-answers; one begins 'I don't have CGEL, but I'm going to answer anyway.'
