I've had these in my .emacs for quite a while and they seem to work:

** ON Load Standard Library of Babel
#+begin_src emacs-lisp :tangle yes
  (org-babel-lob-ingest "~/.emacs.d/src/org-mode/contrib/babel/library-of-babel.org")
#+end_src

** ON Load Local Library of Babel
#+begin_src emacs-lisp :tangle yes
  (org-babel-lob-ingest "~/org/td-lob.org")
#+end_src

hth,
Tom
