Gotta love the beginning of the last sentence of the abstract, ``For

Ironic though that there's what I'd consider a bad page break on pg. 7
(the numbered list at the top of pg. 8 has lost its introductory
paragraph which is at the bottom of the preceding page).

I didn't see a place to get this program from.
For those who're curious, this is a post on this subject I made to
comp.text.tex and later re-posted to TYPO-L:
Subject: page breaking techniques (was Re: License of TeX?)

My take on this is that page breaks have to take into account an entire
chapter---if one is doing a book which opens on any page, well, I've on
occasion gone back and re-run a previous chapter to change the opener
of a chapter to tweak a figure placement early on, so ideally for such
books, one wants to consider the entire text.
Here's a description of the technique I'm using at work on my current
- style the entire chapter, setting the macros appropriately for
anything which doesn't match w/ what the author did. Fix overly wide,
or poorly hyphenated paragraphs at need.
- flip backwards to the beginning, noting if anything is awkward - if
not, you're done (I think this has happened once for a previous project)
- make notes on awkward pages and good pages / spreads, esp. noting
bad figure placement
- from the beginning, adjust to get nice spreads w/ good figure
placement by strategically running spreads long / short (but only
adjusting one increment at a time, so a short spread doesn't back
a long or vice-versa), adjusting paragraph length w/ \looseness,
figure / table placement, creating figure pages at need,
space above heads and around tables and figures &c.
- if one runs into an intractable problem, back up and try a
set of long / short and other tweaks---possibly try running the entire
chapter long / short.
- flip through making sure that no hyphenated words appear at the end
of a recto.
- as a last resort, adjust leading on pages which can't be made to
come out any other way.
