When to cite your sources
Citing the source of information that is not "common knowledge" is always recommended.
Footnotes or Endnotes?

Footnotes generally work better for longer articles and books than endnotes. This is mostly because all the information on a given page remains in context. Folks are more likely to use notes easily located at the bottom of a page. It is just more convenient to look down the page or scroll a short distance than it is to be flipping/clicking back and forth.
For magazine articles (as opposed to journals or books),2 shorter exchanges and family group sheets, endnotes are often the editors preference or the only really practical solution.
A bibliography is a high level list of sources. On a stand alone basis, a bibliography only works well in short articles in my experience. It's a great addition to footnotes or endnotes for a medium sized work or article. For a larger work, you may find it less useful.
