Thanks Don! In defence of Trove, the issue is the quality of the underlying microfilm, which isn't something the digitisation process can sway. I don't know anything about the nuances of the selection process for content used in Trove, but I can tell you that when we have an even selection choice between two titles, one with good microfilm and one a bit rougher but otherwise comparable, we'll opt for the better-quality source. The trove team might have a slightly better budget, so if they get faced with the same choice they might just do both of them :-)
