Do they belong on the ebook thread or the media thread? I'm going to say that these items are closer to non-ebook media than ebooks.
They are very esoteric and specialized, so I'm keeping my fingers crossed that there is someone who will find them helpful.
Wiley Online Library, for what I assume is a limited time, is offering free sample issues of all of the anthropology journals that it publishes (I'm estimating about 50)
here.
It appears that these journals often have some free or open access articles in each issue. Some, but not all. What's different now is it appears that Wiley is offering a large number of entire issues for free. I don't mean just where you can read them on your computer, but a downable (PDF) type of free. Unfortunately, it looks like you may have to download each article separately in order to get a complete issue. But I could be wrong; to be honest, I just haven't explored this all that thoroughly. Frankly, except for some narrow topics, I personally don't have an interest in anthropology.
