The evolution of language is an interesting phenomena and while I'm not doing a university course on the subject, it's something that I find interesting. Not only that, but as Englishmen there exists a cultural heritage aside from the days of the empire and more modern history that shouldn't be forgotten.
While currently between jobs, I have the urge to stimulate my brain with some good old fashioned textbook (I'm open to other means too) learning; to this end, I'm asking for help from those on Warseer who have experience with the subject of the Old English language, or maintain a keen interest themselves, for textbook recommendations. I've searched Amazon (I've not yet journeyed to a library), and I can see a lot to choose from and so I'm a little overwhelmed.
The Cambridge Old English Reader seems like a good start, but some companion reading wouldn't go amiss.
I should say that I currently only have a keen interest and not much in the way of concrete knowledge on the subject, mostly vague information.
