Skip this if not interested.
I'm not sure when Logos shipped this. Maybe a year ago, after Bibleworks died and BW'ers (not Logosians) used it.
But worth some comments, for later searchers.
- It's older, so pre-DSS and prior to the patterns found there. So, some grains of salt.
- The introductions are in german (as the Logos gratifyingly points out). But when you're looking for a manuscript usage, it's worth struggling thru the german. The discussion is in-depth.
- The apparatus is well worth it. Accordance has a tagged Samaritan but no apparatus (that I could see). A variant-MSS seems most valuable with the apparatus, not tagging. Go Logos! (ok, so I'm improperly partisan)
- No english (obviously). I have Benyamin Tsedaka's 'first english translation'. I compared it to the apparatus. Tsedaka bolds significant variances. Personally, the apparatus is more significant. But Tsedaka's notes (extensive) are quite good. So, I'd say 'both'.
- Accordance also offers the Samaritan Targum, just as info. The apparatus refs it also.
Screencopy (mobile!):

And if you sought out Tsedaka, don't forget David Retter's Index to the Talmud (we'll be quiet about Tov):

It's main value is topics (grouping word searches).
