Bertrand, I will answer the second question: yes, Brian generates the "discography" report as a text file (with the extensions .html or .php). You can open this file with your browser and also copy and paste it into Word.
As for the first question, it's been a while since I used Brian for the last time, and so I am not familiar with the latest version, but if I remember correctly, the "Report Tool" used to have different templates: Artist Discography, Musicians, Tunes played... I guess it also allows for a Label report.
