I'd like to bring your attention to an experimental project I have been working on for a while: an edition of the first book of the Annals by Tacitus, with commentaries and explanations purely in Latin, and everything illustrated with recordings of the original text:
http://la.wikibooks.org/wiki/Taciti_Ann ... ber_Primus
The annotations (which are not complete, I might add) mostly deal with explaining vocabulary and grammatical constructions. But, since the text is placed on a wiki, anyone can edit it, so feel free to add (or correct) comments and explanations, as you see fit.
If there is some aspect of the text you don't understand, you can always add a note containing only a question, and then someone else can fill in an explanation.
The audio files, in different formats, can also be downloaded here:

If you find a erronous vowel quantity in the text, or in my recordings, or for that matter a wrongly placed stress, or where my phrasing reveals that I have misunderstood the construction of the Latin, I would be very grateful if you would report them, and then I will redo the recording.
