It's deja vu all over again. The first OPAC I ever installed, DOBIS,
allowed one to enter a browse list through any term in a heading,
by using a keyword in context browse (KWIC) display. By placing the
word from the heading that most closely matched the search term 1/3
across the screen, the user could see both what was to its left (if
anything) as well as what followed. This served both discoverability
of terms inside headings and the sequential browsing structure.

We use a rotated headings feature in our current Unicorn catalog
for much the same reason for the subjects browse index, although
the display is left-anchored, which makes it less obvious that
terms have been rotated (e.g., 3-5, below):

1) Civil war. [52]
2) see related headings for: Civil war
3) Civil War, 43-31 B.C.--Drama. Rome--History [6]
4) Civil War, 43-31 B.C.--Fiction. Rome--History [1]
5) Civil War, 43-31 B.C.--Historiography. Rome--History [5]

This is a true browse list, in that you can page forward and
backward indefinitely.

Whatever the considerable benefits of browse displays (I read, and
took to heart Thomas Mann's comments), the fact remains that, when
I look at our search log stats, users (as opposed to librarians)
simply do NOT browse (and it's not for lack of instruction).

June search stats:

All Searches Total      90,280
        Browse Total     4,877
        Author             791
        Title            2,628
        Periodical Title 1,217
        Series              46
        Subject            190
        Other                5

Looking at the actual terms that people are entering, I'm willing
to speculate that library staff account for as much browsing activity
as all other users combined, which makes the discrepancy even greater.
