Errata For A Reader’s Greek New Testament

As I was reading through 1 Thessalonians this morning, I stumbled across a mistake in the text.  In chapter 4 verse 11, a portion of the text reads: “καὶ ἐργάζεσθαι ταῖς χερσὶν✝ὑμῶν.” The problem is bolded, there needs to be a space after χερσὶν✝. The ✝ denotes a deviation from the UBS text, and normally there are spaces the symbol, but not here.

On another note, is there any rhyme or reason to how they write UBS at the bottom of the page? Usually the UBS reading is followed by “(UBS).” However, there are several points where it’s transliterated into Greek: “ὙΒΣ.” Seems this seems rather odd to me.

I love this handy little volume, but it does look like there is room for improvement in version 3. Is there any formal way to submit little bugs like these?
