What is the different between reference list and bibliography

The reference list is for listing the source of info used in a written work. A bibliography is a listing of information sources used for information for the written work whose content is not used the in that work. In an example, "Using the 5/8" box end wrench, remove the fastener." printed in a book and then used verbatim in the written work, would be referenced. But the book read that has that sentence would be bibliographed.
