Editing Rutherford is not easy, and the venture hard to justify except for perhaps a university press or seminary given the number of cheap copies around. Or maybe the only way to justify it would be to include it in a uniform set of his works. Someone should try to do a uniform set of new editions of Rutherford's works.
I wish it was generally available in full size rather than shrunk down like it is. Having edited Gillespie's English Popish Ceremonies that was also prepared for the same set (the 3 volume Presbyterian's Armoury put out by the Free Church under Hetherington's editorship), I can say that it would not hurt to have a new edition. Plus, it could use some of thing helps as I added to the NP Gillespie such as full critical bibliography, index etc. I think the worst error I found in the Gillespie was a full missing sentence or halves of two sentences. Because of that I would suspect a new critical edition is warranted to check and make sure nothing similar occured in the Rutherford. The NP Gillespie also has all the Latin translated and I don't recall about Lex Rex but if it is as extensive that would be helpful too.
