I ended up with this. It's not so bad, Though I use it enough that I
should probably just define another function. Also, I'm interested in how 2
source blocks would have worked...
#+BEGIN_SRC elisp :results output raw
(let ((sources '(
"/home/matt/HackingHistory/readings/Troper-becoming-immigrant-city.pdf"
"/home/matt/HackingHistory/readings/historical-authority-hampton.pdf"))
(output ""))
(dolist (thispdf sources)
(message "this pdf is: %s" thispdf)
(setq output (concat output (pdf-annot-markups-as-org-text thispdf
))))
(princ output))
#+END_SRC

:results value raw works -- thank you!

Can I pass the level of the current heading as a parameter, e.g.:
#+BEGIN_SRC elisp :results output raw :var level=(1+ CURRENT-ORG-LEVEL)
where obviously CURRENT-ORG-LEVEL is some function I don't know how to
access?
Many thanks for your help, Nick!
