+</pre></div>
+
+<p>The <code>\baselineskip</code> is a rubber length (see <a href="#Lengths">Lengths</a>). It gives
+the leading, the normal distance between lines in a paragraph, from
+baseline to baseline.
+</p>
+<p>Ordinarily document authors do not directly change <code>\baselineskip</code>
+while writing. Instead, it is set by the low level font selection
+command <code>\fontsize</code> (see <a href="#low-level-font-commands-fontsize">low level font commands fontsize</a>).
+The <code>\baselineskip</code>’s value is reset every time a font change
+happens and so any direct change to <code>\baselineskip</code> would vanish
+the next time there was a font switch. For how to influence line
+spacing, see the discussion of <code>\baselinestretch</code> below.
+</p>
+<p>Usually, a font’s size and baseline skip is assigned by the font
+designer. These numbers are nominal in the sense that if, for instance,
+a font’s style file has the command <code>\fontsize{10pt}{12pt}</code>
+then that does not mean that the characters in the font are 10pt tall;
+for instance, parentheses and accented capitals may be taller. Nor does
+it mean that if the lines are spaced less than 12pt apart then they risk
+touching. Rather these numbers are typographic judgements. (Often, the
+<code>\baselineskip</code> is about twenty percent larger than the font size.)
+</p>
+<p>The <code>\baselineskip</code> is not a property of each line but of the
+entire paragraph. As a result, large text in the middle of a paragraph,
+such as a single <code>{\Huge Q}</code>, will be squashed into its line.
+TeX will make sure it doesn’t scrape up against the line above but
+won’t change the <code>\baselineskip</code> for that one line to make extra
+room above. For the fix, use a <code>\strut</code> (see <a href="#g_t_005cstrut">\strut</a>).
+</p>
+<p>The value of <code>\baselineskip</code> that TeX uses for the paragraph is
+the value in effect at the blank line or command that ends the paragraph
+unit. So if a document contains this paragraph then its lines will be
+scrunched together, compared to lines in surrounding paragraphs.
+</p>
+<div class="example">
+<pre class="example">Many people see a page break between text and a displayed equation as
+bad style, so in effect the display is part of the paragraph.
+Because this display is in footnotesize, the entire paragraph has the
+baseline spacing matching that size.
+{\footnotesize $$a+b = c$$}
+</pre></div>
+
+<p>The process for making paragraphs is that when a new line is added, if
+the depth of the previous line plus the height of the new line is less
+than <code>\baselineskip</code> then TeX inserts vertical glue to make up
+the difference. There are two fine points. The first is that if the
+lines would be too close together, closer than <code>\lineskiplimit</code>,
+then TeX instead uses <code>\lineskip</code> as the interline glue. The
+second is that TeX doesn’t actually use the depth of the previous
+line. Instead it uses <code>\prevdepth</code>, which usually contains that
+depth. But at the beginning of the paragraph (or any vertical list) or
+just after a rule, <code>\prevdepth</code> has the value -1000pt and that
+keeps TeX from inserting any interline glue at the paragraph start.
+</p>
+<p>In the standard classes <code>\lineskiplimit</code> is 0pt and
+<code>\lineskip</code> is 1pt. By the prior paragraph then, the distance
+between lines can approach zero but if it equals zero then the lines
+jump to 1pt apart.
+</p>
+<p>Sometimes authors must, for editing purposes, put the document in double
+space or one-and-a-half space. The right way to influence the interline
+distance is via <code>\baselinestretch</code>. It scales
+<code>\baselineskip</code>, and has a default value of 1.0. It is a command,
+not a length, so change the scale factor as in
+<code>\renewcommand{\baselinestretch}{1.5}\selectfont</code>.
+</p>
+<p>The most straightforward way to change the line spacing for an entire
+document is to put <code>\linespread{<var>factor</var>}</code> in the preamble.
+For double spacing, take <var>factor</var> to be 1.6 and for one-and-a-half
+spacing use 1.3. These number are rough: for instance, since the
+<code>\baselineskip</code> is about 1.2 times the font size, multiplying by
+1.6 gives a font size to baseline ratio of about 2. (The
+<code>\linespread</code> command is defined as
+<code>\renewcommand{\baselinestretch}{<var>factor</var>}</code> so it won’t
+take effect until a font setting happens. But that always takes place at
+the start of a document, so there you don’t need to follow it with
+<code>\selectfont</code>.)
+</p>
+<p>A more flexible approach is the <samp>setspace</samp> package. After the
+<code>\usepackage{setspace}</code>, use <code>\doublespacing</code>, or
+<code>\onehalfspacing</code> or one-an-a-half. In the preamble these will
+start the document off with that sizing. But you can also use these
+declarations in the document body to change the spacing from that point
+forward, and consequently there is <code>\singlespacing</code> to return the
+spacing to normal. In the document body, a better practice than using
+the declarations is to use environments, such as
+<code>\begin{doublespace} ... \end{doublespace}</code>. The package also
+has commands to do arbitrary spacing: <code>\setstretch{<var>factor</var>}</code>
+and <code>\begin{spacing}{<var>factor</var>} ... \end{spacing}</code>.

+Synopsis: to change the document spacing put this in the preamble.
+
+ \usepackage{setspace}
+ \doublespacing % or \onehalfspacing for 1.5
+
+ The '\baselineskip' is a rubber length (*note Lengths::). It gives
+the leading, the normal distance between lines in a paragraph, from
+baseline to baseline.
+
+ Ordinarily document authors do not directly change '\baselineskip'
+while writing. Instead, it is set by the low level font selection
+command '\fontsize' (*note low level font commands fontsize::). The
+'\baselineskip''s value is reset every time a font change happens and so
+any direct change to '\baselineskip' would vanish the next time there
+was a font switch. For how to influence line spacing, see the
+discussion of '\baselinestretch' below.
+
+ Usually, a font's size and baseline skip is assigned by the font
+designer. These numbers are nominal in the sense that if, for instance,
+a font's style file has the command '\fontsize{10pt}{12pt}' then that
+does not mean that the characters in the font are 10pt tall; for
+instance, parentheses and accented capitals may be taller. Nor does it
+mean that if the lines are spaced less than 12pt apart then they risk
+touching. Rather these numbers are typographic judgements. (Often, the
+'\baselineskip' is about twenty percent larger than the font size.)
+
+ The '\baselineskip' is not a property of each line but of the entire
+paragraph. As a result, large text in the middle of a paragraph, such
+as a single '{\Huge Q}', will be squashed into its line. TeX will make
+sure it doesn't scrape up against the line above but won't change the
+'\baselineskip' for that one line to make extra room above. For the
+fix, use a '\strut' (*note \strut::).
+
+ The value of '\baselineskip' that TeX uses for the paragraph is the
+value in effect at the blank line or command that ends the paragraph
+unit. So if a document contains this paragraph then its lines will be
+scrunched together, compared to lines in surrounding paragraphs.
+
+ Many people see a page break between text and a displayed equation as
+ bad style, so in effect the display is part of the paragraph.
+ Because this display is in footnotesize, the entire paragraph has the
+ baseline spacing matching that size.
+ {\footnotesize $$a+b = c$$}
+
+ The process for making paragraphs is that when a new line is added,
+if the depth of the previous line plus the height of the new line is
+less than '\baselineskip' then TeX inserts vertical glue to make up the
+difference. There are two fine points. The first is that if the lines
+would be too close together, closer than '\lineskiplimit', then TeX
+instead uses '\lineskip' as the interline glue. The second is that TeX
+doesn't actually use the depth of the previous line. Instead it uses
+'\prevdepth', which usually contains that depth. But at the beginning
+of the paragraph (or any vertical list) or just after a rule,
+'\prevdepth' has the value -1000pt and that keeps TeX from inserting any
+interline glue at the paragraph start.
+
+ In the standard classes '\lineskiplimit' is 0pt and '\lineskip' is
+1pt. By the prior paragraph then, the distance between lines can
+approach zero but if it equals zero then the lines jump to 1pt apart.
+
+ Sometimes authors must, for editing purposes, put the document in
+double space or one-and-a-half space. The right way to influence the
+interline distance is via '\baselinestretch'. It scales
+'\baselineskip', and has a default value of 1.0. It is a command, not a
+length, so change the scale factor as in
+'\renewcommand{\baselinestretch}{1.5}\selectfont'.
+
+ The most straightforward way to change the line spacing for an entire
+document is to put '\linespread{FACTOR}' in the preamble. For double
+spacing, take FACTOR to be 1.6 and for one-and-a-half spacing use 1.3.
+These number are rough: for instance, since the '\baselineskip' is about
+1.2 times the font size, multiplying by 1.6 gives a font size to
+baseline ratio of about 2. (The '\linespread' command is defined as
+'\renewcommand{\baselinestretch}{FACTOR}' so it won't take effect until
+a font setting happens. But that always takes place at the start of a
+document, so there you don't need to follow it with '\selectfont'.)
+
+ A more flexible approach is the 'setspace' package. After the
+'\usepackage{setspace}', use '\doublespacing', or '\onehalfspacing' or
+one-an-a-half. In the preamble these will start the document off with
+that sizing. But you can also use these declarations in the document
+body to change the spacing from that point forward, and consequently
+there is '\singlespacing' to return the spacing to normal. In the
+document body, a better practice than using the declarations is to use
+environments, such as '\begin{doublespace} ... \end{doublespace}'. The
+package also has commands to do arbitrary spacing: '\setstretch{FACTOR}'
+and '\begin{spacing}{FACTOR} ... \end{spacing}'.

+ at end example
+
+The @code{\baselineskip} is a rubber length (@pxref{Lengths}). It gives
+the leading, the normal distance between lines in a paragraph, from
+baseline to baseline.
+
+Ordinarily document authors do not directly change @code{\baselineskip}
+while writing. Instead, it is set by the low level font selection
+command @code{\fontsize} (@pxref{low level font commands fontsize}).
+The @code{\baselineskip}'s value is reset every time a font change
+happens and so any direct change to @code{\baselineskip} would vanish
+the next time there was a font switch. For how to influence line
+spacing, see the discussion of @code{\baselinestretch} below.
+
+Usually, a font's size and baseline skip is assigned by the font
+designer. These numbers are nominal in the sense that if, for instance,
+a font's style file has the command @code{\fontsize@{10pt@}@{12pt@}}
+then that does not mean that the characters in the font are 10pt tall;
+for instance, parentheses and accented capitals may be taller. Nor does
+it mean that if the lines are spaced less than 12pt apart then they risk
+touching. Rather these numbers are typographic judgements. (Often, the
+ at code{\baselineskip} is about twenty percent larger than the font size.)
+
+ at c adapted from FAQ
+The @code{\baselineskip} is not a property of each line but of the
+entire paragraph. As a result, large text in the middle of a paragraph,
+such as a single @code{@{\Huge Q@}}, will be squashed into its line.
+ at TeX{} will make sure it doesn't scrape up against the line above but
+won't change the @code{\baselineskip} for that one line to make extra
+room above. For the fix, use a @code{\strut} (@pxref{\strut}).
+
+The value of @code{\baselineskip} that @TeX{} uses for the paragraph is
+the value in effect at the blank line or command that ends the paragraph
+unit. So if a document contains this paragraph then its lines will be
+scrunched together, compared to lines in surrounding paragraphs.
+
+ at c Adapted from B Beeton's "Lapses in TeX" TB 42,1 p 13.
+ at example
+Many people see a page break between text and a displayed equation as
+bad style, so in effect the display is part of the paragraph.
+Because this display is in footnotesize, the entire paragraph has the
+baseline spacing matching that size.
+@{\footnotesize $$a+b = c$$@}
+ at end example
+
+The process for making paragraphs is that when a new line is added, if
+the depth of the previous line plus the height of the new line is less
+than @code{\baselineskip} then @TeX{} inserts vertical glue to make up
+the difference. There are two fine points. The first is that if the
+lines would be too close together, closer than @code{\lineskiplimit},
+then @TeX{} instead uses @code{\lineskip} as the interline glue. The
+second is that @TeX{} doesn't actually use the depth of the previous
+line. Instead it uses @code{\prevdepth}, which usually contains that
+depth. But at the beginning of the paragraph (or any vertical list) or
+just after a rule, @code{\prevdepth} has the value -1000pt and that
+keeps @TeX{} from inserting any interline glue at the paragraph start.
+
+In the standard classes @code{\lineskiplimit} is 0pt and
+ at code{\lineskip} is 1pt. By the prior paragraph then, the distance
+between lines can approach zero but if it equals zero then the lines
+jump to 1pt apart.
+
+Sometimes authors must, for editing purposes, put the document in double
+space or one-and-a-half space. The right way to influence the interline
+distance is via @code{\baselinestretch}. It scales
+ at code{\baselineskip}, and has a default value of 1.0. It is a command,
+not a length, so change the scale factor as in
+ at code{\renewcommand@{\baselinestretch@}@{1.5@}\selectfont}.
+
+The most straightforward way to change the line spacing for an entire
+document is to put @code{\linespread@{@var{factor}@}} in the preamble.
+For double spacing, take @var{factor} to be 1.6 and for one-and-a-half
+spacing use 1.3. These number are rough: for instance, since the
+ at code{\baselineskip} is about 1.2 times the font size, multiplying by
+1.6 gives a font size to baseline ratio of about 2. (The
+ at code{\linespread} command is defined as
+ at code{\renewcommand@{\baselinestretch@}@{@var{factor}@}} so it won't
+take effect until a font setting happens. But that always takes place at
+the start of a document, so there you don't need to follow it with
+ at code{\selectfont}.)
+
+A more flexible approach is the @file{setspace} package. After the
+ at code{\usepackage@{setspace@}}, use @code{\doublespacing}, or
+ at code{\onehalfspacing} or one-an-a-half. In the preamble these will
+start the document off with that sizing. But you can also use these
+declarations in the document body to change the spacing from that point
+forward, and consequently there is @code{\singlespacing} to return the
+spacing to normal. In the document body, a better practice than using
+the declarations is to use environments, such as
+ at code{\begin@{doublespace@} ... \end@{doublespace@}}. The package also
+has commands to do arbitrary spacing: @code{\setstretch@{@var{factor}@}}
+and @code{\begin@{spacing@}@{@var{factor}@} ... \end@{spacing@}}.
