 A font, on the other hand, actually refers to a collection of characteristics, including shape, series, and size. ``Times New Roman'' is a typeface; ``Times New Roman bold italic 10 point'' is a font. This distinction goes back to the days when typefaces were physical objects made of lead. 
 
+Typefaces fall into a number of different categories, including serif, sans-serif, proportional, and monospace. 
+
+A serif font has small decorative lines attached to the ends of letters, whereas a sans-serif font does not. This zine is typeset using the \textsf{kpfonts} package, which uses serif fonts that were originally derived from the URW Palladio font\footnote{See \kref{https://fontesk.com/palladio-typeface/}{https://fontesk.com/palladio-typeface/} and \kref{https://ctan.org/tex-archive/fonts/kpfonts?lang=en}{https://ctan.org/tex-archiv\\e/fonts/kpfonts?lang=en}.} so all the letters you see here have serifs. I also use the Cantarell font in some places, which is a sans-serif font.\footnote{See \kref{https://ctan.org/tex-archive/fonts/cantarell?lang=en}{https://ctan.org/tex-archive/fonts/cantarell?lang=en}.} \textsf{This sentence is typeset in a sans-serif font.}
+
+In a proportional font, each letter takes up a different width. Some letters, such as \textsf{m} and \textsf{w}, are fairly wide, whereas other, such as \textsf{i} and \textsf{l}, are fairly narrow, and most other letters are somewhere in between. In a monospace font, each letter takes up the same exact width. The \textsf{kpfonts} package I use for the text in this zine is a proportional font, but the code samples are in a monospace font. \texttt{This sentence is typeset in a monospace font.} Typewriters typically use a monospace font, but as computers became commonly available, a few of them could actually type in a proportional font.\footnote{Typewriters are a particular love of mine, and I can go on about them at considerable length. Don't get me started.}

 \section{Shape}
 
-The \textit{shape} of a font refers to how the individual characters are formed.\footnote{This is a terrible definition, but it is what it is. I didn't make the rules here.} Shape can be upright (i.e., ``normal''), italic, slanted, and small caps.

-Both italic and slanted shapes lean to the right. The main difference between the two occurs when you apply this to a \textit{serif} typeface—that is, a typeface that has little bits regularly attahced to the end of a larger stroke. A slanted shape is just that: it's as if you had written out the text on a flexible substrate and then just stretched it a bit so it leans to the right. An italic shape, however, actually has completely different, somewhat more curvy shape to each character.

An italic shape, however, actually has a completely different, somewhat more curvy shape to each character. Italic or oblique shapes are often used to emphasize a word or group of words (i.e., ``This is \textit{very} good cake.'') but it also used by convention to indicate the titles of books and movies (i.e., \textit{The Grapes of Wrath}, \textit{Star Wars}).
 
-This is what they look like in a Roman (i.e., a ``serif'' typeface):
+Small caps is shorthand for ``small capitals'' and refers to text in which all the lower-case characters are substituted by their upper-case equivalents. \textsc{This text is in small caps.} Small caps is often used to convey prestige and stability.

+It's interesting to note that in the Cantarell typeface, the italic and the slanted shapes are pretty much identical, and it also doesn't include a small caps version at all. Some font packages include these, and some do not. As always, you should read the font documentation to see what is included.
