First Logos then Verbum software have carried me through two graduate programs and two theses, as well as 11 years of clerical ministry. It's an excellent tool, and the commentaries and dictionaries are so excellent for theological and linguistic research and analysis.
I do wish that certain publication editions were kept more up to date. Specifically, the version of the 1983 CIC in Verbum does not include the most recent updates introduced by Mitis Iudex Dominus Iesus and Vos Estis Lux Mundi. These change procedural law significantly and would be very good to have for canonical research.
