For reasons that are not at all clear, but that may be connected to the recent WordPress format updates, my tests of the links in the post – whether posted today or earlier – are not working to open up the PDF files so that they can be read. External links – the NPR stories and the extemp files link – are working. Until I can figure out what happened, you can find any of the articles I posted in the appropriate extemp file subfolder.
Update: This isn’t, apparently, the only blog to which this is happening, and WordPress finally seems aware of the problem. No estimated date of repair yet, though.
