The first looks like something I might use with my kids after they get through their Hebrew Grammar and Vocab. It looks like something one might use in a seminary introduction class that was only a semester long, but we'll see. The second, I think, is more a source that I would use in a year-long class and also for personal reference (Huehnergard is a prof at Harvard and knows how to write understandable and informative introductory grammars for students--his Akkadian grammar is great as an introduction to grammar and vocab). Ugaritic is a big help in understanding Semitic languages in general, which also then helps understand a lot about Classical Hebrew, specifically Early Biblical Hebrew in the case of Ugaritic. I hope to get these at some point and review them here.
