An embedded links seems to be prefer by users in at least one study. The
Usability Lab at Wichita did some research into link location some time ago (It
is Michael Bernard, Spring Hull, & Denise Drake's classic 2001 study). They
studied academic type information - the sort you'd expect a user to read much
on screen as they would on paper (ie skim first, then in detail, in the "right"
order).

Their conclusions:

"Several observations can be made from this study. First, no significant
differences between the four link arrangements were detected in terms of search
accuracy, time, or efficiency. This suggests that the link arrangement for
documents within a single frame does not have a great affect on its actual
navigability."

"However, there were significant subjective differences between the link
arrangements favoring the embedded links. That is, participants indicated that
they believed that embedding the links within a document made it easier to
navigate, easier to recognize key information, easier to follow the main idea
of the passages, and promoted comprehension. Moreover, participants
significantly preferred the Embedded link arrangement to the other
arrangements. Conversely, placing links at the bottom of a document was
perceived as being the least navigable arrangement, and was consequently least
preferred."

"Although no significant objective differences were found, the consistent
results of the subjective perceptions of link navigability, as well as general
preference, suggest that the Embedded link arrangement is perceived as being
the superior format for online documents within a single frame. For this
reason, it is suggested that for documents using a format similar to the type
tested in this study, embedded links should be considered."
