Footnotes, endnotes or online notes?

[STS Lincolnite]

After receiving it as a gift a while back, I pulled Daniel Stashower’s The Hour of Peril out of my “to read” pile and started to page through it. I noticed that there was no internal reference structure and no endnotes or footnotes (at least in the hardcover edition that I have). After a little internet searching, I found that the “source notes” are available online (I had not seen that before related to a historical text publication). You can find the source notes here:

The book, what little I have read of it so far, is interesting.

Anyway, I started to think about these reference/source notes and which I and others might prefer: footnotes, endnotes or the aforementioned online source notes. Or maybe some prefer no notes at all.

What does everyone prefer or not prefer and why or why not!
