I had a look through the .pdf copy of his A catalogue of Greek verbs. For the use of colleges (1844).
If I had been introduced to this work at college (University), I would not have had the need (or competency) to use it till my third year of Greek. The work assumes the reader has mastered a basic classical Greek vocabulary of (I estimate) at least 750 words, is able to both parse and compose forms, and has a basic recognition of which words belong to prose and which belong to verse - which recognition requires both reading experience / familiarity with the the classical "canon" and direct learning of both vocabulary and inflectional forms applicable to both genres. The central catalogue of verbs seems straightforward enough for a user with that background.
On the positive side, I like it because Sophocles doesn't frequently compare Greek grammar to Latin - frequent references to Latin are a chore rather than an aid for me, becuase I double majored in Greek and Modern Greek (rather than Latin). I particularly like the practice of capitalising "obsolete and imaginary presents" mentioned at the beginning of the catalogue section.
While I find the tabulated layout of A Catalogue of Greek Verbs, Irregular and Defective by James Skerrett S. Baird easier to flip through, I like Sophocles more "talkative" style of paragraph presentation for thinking things through.https://archive.org/stream/catalogueofg ... 6/mode/2up
On the negative side, it seems that a user needs to have feel for the book itself to get the most out of it. The "Remarks" at the beginning present an analysis of verbal forms that might overwhelm someone starting there. The appendicies (especially the chrestomathy of inscriptions don't seem to have a direct relationship to the central catalogue of verbs (as interesting as they are in themselves they seem suited to a more comprehensive grammar-come-reader).
I would be interested to know how this work with it disjointed parts will be going to be presented in the software package on offer - especially how the seemingly disjointed parts are going to be worked together in a digital version.
