A commenter jarred my mind to recall that ETS (Evangelical Theological Society) sessions are recorded as MP3 files by a company who’s done that for years. Click here for that website. The link leads you to a “pre-pub” offer for this year’s event, plus previous years. Since NEAS (Near East Archaeological Society) shares the venue with ETS, I am assuming NEAS sessions are included in the recording — but I’m not completely certain.
There is no similar recording at SBL, IBR, or ASOR to my knowledge.
