Doing M-x org-babel-lob-files called up a customization buffer that allowed
me to put in many separate file paths. I did this for ../a.org and ../b.org.

a.org:

#+name: myadd
#+begin_src lisp :session
(defun myadd (x y)
  (+ x y))
#+end_src

b.org:

#+name: multi_x2
#+begin_src lisp :session
(defun multi_x2 (x)
  (* 2 x))
#+end_src

then in c.org:

#+name: add&multi_x2
#+begin_src lisp :session
(defun add&multi_x2 (x y)
  (multi_x2 (myadd x y)))
#+end_src

but upon C-c C-c in c.org SLIME didn't know about myadd or multi_x2 ...
until I did C-c C-c in both a.org and b.org for the respective functions.
Then c.org's add&multi_x2 knew about the helper functions. That is
wonderful and allows a very distributed and modular approach to org-mode LP
for Lisp. However, it would be nice if I didn't have to acquaint my SLIME
session by hand all of my ingested babel-lob files. Any way to have this
happen automatically upon C-c C-c-ing my main org file? I found this
<https://lists.gnu.org/archive/html/emacs-orgmode/2010-09/msg01172.html>
discussion,
but I don't believe it really addresses my wish.
