I have modified TUGBOT.STY to switch between one and two columns
in the middle of a page using the method outlined in the TeXbook
and TUGboat v.6 #1 pg 30.  I have produced the files TWO.STY and
TWO.DOC. The latter contains examples of some of the less
obvious features.

%       Struts give ascenders and descenders to assist in baseline alignment
%       (e.g. of adjoining vertical boxes); useful only with text fonts.
%
%       \strut is defined in PLAIN .  The structure of \strutt is equivalent.

\newbox\struttbox
\def\strutt{\relax\ifmmode\copy\struttbox\else\unhcopy\struttbox\fi}

%       Struts are given the following dimensions for use in TUGboat:
%
%               \strut = height/depth of parenthesis in current font
%                        (not the same as PLAIN)
%               \strutt height + depth = \normalbaselineskip,
%                        height = same as \strut
%                        (equivalent to PLAIN \strut )


%       The fonts below are sufficient for most ordinary TUGboat production.
%       Additional titling fonts are defined elsewhere, and occasionally an
%       extra font will be needed for a particular item (e.g. the device
%       charts) and defined in that file.

\title Where It Comes From\\Ted Shapin\endx
TWO.STY is a modification of TUGBOT.STY that allows switching from one
column to two columns and back in the middle of a page.  It uses the
method described in the \TeX book as modified in Tugboat v.~6, no.~1,
page 30.

\subtitle This Is A Very Long Subtitle\cr So We'll Put It On Two Lines\endx

The macros I added are called $\backslash$twocol to change to two columns and
$\backslash$onecol to change to one column.  I added a test that will
print an error message if you try to change to a mode you are already in.

I also made some minor changes to TUGBOT.STY.  I made the box around the
section titles a little shorter, and reduced the skip before them to 3 lines.

I let the masthead be defined and called as regular text outside of the style.
\onecol
\title TUGBOT Style\\\endx

Here are some comments from Barbara Beeton on the original TUGBOT.STY
which will help you use some of the features [all the changes are my own 
fault]:

\begintt

Paragraphs don't flush left after \sectitle, only after \title .
\title ia a 2-parter -- \title #1\\#2[author]\endx . 
Multi-line title and author parts are split by \cr ; 
this is probably a bit weird, but it's an artifact of an earlier 
version that used \halign . 
Because the article on pages 104 ff. of tb 7#2 seems to have the sorts
of things you're looking for, I've stripped it down to contain one each
of the interesting stuff, and here are the remains:
