Aloha Lawrence,
You probably want (org-babel-lob-ingest &optional FILE)
All the best,
Tom

Thanks for the help. However, one mystery still remains: Why is this
'(org-babel-lob-files (quote ("~/org/worg/library-of-babel.org ")))
in my init.el's custom-set-variables not getting handled? I always have to
do an org-babel-lob-ingest to actually get library-of-babel.org loaded.

`C-h k' is really your friend here. If you do not know it, try typing it
twice `C-h k C-h k'.
As for the specific keystrokes mentioned above:
,----[ C-h k C-c C-v v ]
| C-c C-v v runs the command org-babel-expand-src-block (found in
| org-mode-map), which is an interactive autoloaded compiled Lisp
| function in ‘ob-core.el’.
|
| It is bound to C-c C-v v, C-c C-v C-v.
|
| (org-babel-expand-src-block &optional ARG INFO PARAMS)
|
| Expand the current source code block.
| Expand according to the source code block’s header
| arguments and pop open the results in a preview buffer.
|
| [back]
`----
In your case, it shows that the `mtelsquare' src block expands to:
,----
| (let ((x (quote 0)))
| (defun myelsquare (x)
| (* x x))
| )
`----
,----[ C-h k C-x C-e ]
| C-x C-e runs the command eval-last-sexp (found in global-map), which
| is an interactive compiled Lisp function in ‘elisp-mode.el’.
|
| It is bound to C-x C-e.
|
| (eval-last-sexp EVAL-LAST-SEXP-ARG-INTERNAL)
|
| Evaluate sexp before point; print value in the echo area.
| Interactively, with prefix argument, print output into current buffer.
|
| Normally, this function truncates long output according to the value
| of the variables ‘eval-expression-print-length’ and
| ‘eval-expression-print-level’.With a prefix argument of zero,
| however, there is no such truncation. Such a prefix argument
| also causes integers to be printed in several additional formats
| (octal, hexadecimal, and character).
|
| If ‘eval-expression-debug-on-error’ is non-nil, which is the default,
| this command arranges for all errors to enter the debugger.

`----
So with point at the end of the preview buffer for myelsquare (which has
one `let' expression it it) it has the same effect as running
`eval-buffer'. viz, the elisp function `myelsquare' is created.
If you have gotten this far, there is an lisp function called `myelsquare'
and the `symbol-function' expression will return its value when properly
`eval'ed. I misspoke before. I should have said
M-: (symbol-function 'myelsquare) RET
And that value is `(lambda (x) (* x x))'. Which simply shows you have
defun'ed a function and what it is.
Once you have an elisp function, the natural way to call it is
src_emacs-lisp{(myelsquare 1.5)}.
One thing you can do with LOB blocks is use them in header args of src
blocks just as you would use calls to ordinary src blocks.
HTH,
Chuck
