This is the official manual for the latest Org-mode release.
The “Library of Babel” is a collection of code blocks available for calling from other Org files. This collection is in a repository file in Org mode format in the ‘doc’ directory of Org mode installation. For remote code block evaluation syntax, see Evaluating code blocks.
For user's to add their own code blocks to the library, first save the code
in an Org file, and then load it with
org-babel-lob-ingest, which is
bound to C-c C-v i.
