For those interested, here's a list of the novels, novelizations, trilogies and short stories. Posted with permission of KoshN over at B5TV.com:
The Dell novels (except 7 and 9) are what JMS said were only "canon in broad strokes". The trilogies were written from extensive outlines by JMS. "To Dream in the City of Sorrows" was written by the then-Mrs. JMS
NOVELS: (Dell Books #7 and #9, and the three Del Rey Trilogies are considered canon. I would say that the short stories are also canon, except possibly "Space, Time, and the Incurable Romantic" which is more of a flight of fancy written to satisfy Ivanova/Marcus "shippers.") (NOTE: JMS has said it's canon. ~~Jan)
