# Lest we forget: Typography & LaTeX

Martins Bruveris recently gave an introductory lecture on LaTeX at Brunel University, and the deck was based on my previous LaTeX: More Than Just Academic Papers and Theses slides. (Suffice to say that I’m extremely happy that people are still reading it since I first made it in 2011—I’ve since updated it a bit.)

I particularly like how Martins highlighted how important typography is in retaining the readers’ (ahem supervisors, examiners, reviewers…) interest/attention. That’s so true—I remain certain that I received an award for my paper at a student workshop, partly (or perhaps majorly) because I used LaTeX. One of the panels commented “it’s a very clear, very nice paper—not sure why but it was just very enjoyable to read.”

Lest we’ve forgotten at times amid all the exciting new packages in recent years that let us do various cool things in LaTeX, typography is why Knuth created TeX in the beginning, and why some (I’ll acknowledge not all) users prefer LaTeX over word processors. Martins included this quote on typography in his slides:

Typography matters because it helps conserve the most valuable resource you have as a writer—reader attention.
Attention is the reader’s gift to you. That gift is precious. It is finite. And if you fail to be a respectful steward of that gift, it will be revoked.
(Matthew Butterick, Typography for Lawyers)

I would add this quote by Robert Bringhurst in the opening chapter to The Elements of Typographic Style:

Like oratory, music, dance, calligraphy—like anything that lends its grace to language—typography is an art that can be deliberately misused. It is a craft by which the meanings of a text (or its absence of meaning) can be clarified, honored and shared, or knowingly disguised.

and later in Chapter 10:

Writing begins with the making of meaningful marks. That is to say, leaving the traces of meaningful gestures. Typography begins with arranging meaningful marks that are already made. In that respect, the practice of typography is like playing the piano—an instrument quite different from the human voice.

And personally, I do think writings convey the experience knowledge of humankind (I know that sounds a bit pompous, spare me the rod), and deserve to be typeset with ultimate quality for an enjoyable reading experience!

# Paragraph indents and spacing

By default, LaTeX does not indent the first paragraph after a section command, but will indent all subsequent paragraphs.

You can, of course, add `\indent` to the start of each first paragraph. But that gets rather tedious after a while, and you might miss it if e.g. some time later, you add another paragraph immediately after the sectioning command.

Fortunately, the `indentfirst` package will do this automatically for you — rejoice!

If you need to change the indent amount (for all paragraphs), you can set the `\parindent` length:

`\setlength{\parindent}{2em}`

The inevitable next question: “What if I need to have some space between the paragraphs?”

Rule: Please don’t use `\\\\` to achieve “space between paragraphs”. Please. Don’t.

`\\` is for line breaks. Paragraph breaks in LaTeX are done by either leaving a blank line in the source code, or by using `\par`. Line breaks and paragraph breaks are two very, very distinct concepts in typesetting, and are handled differently in LaTeX.

So the easiest way to achieve this is simply by writing `\usepackage{parskip}`. This avoids modifying the `\parskip` length directly, because `\parskip` has consequences for many other constructs, e.g. `itemize` and `enumerate` lists.

If you happen to be using one of the Koma-Script document classes, you may get a warning message when you try to load `parskip`. In that case, just pass `parskip` as a document class option, e.g. `\documentclass[parskip]{scrbook}`.

If `memoir` is the document class in use instead, you can write `\nonzeroparskip` or `\abnormalparskip{\baselineskip}`.

Just take note: it’s usually considered redundant to have both non-zero paragraph spacing and paragraph indents, so all paragraph indents are suppressed when `parskip` is loaded. Having said that, if you do need the paragraphs to be indented as well (university thesis requirements), use the `\setlength{\parindent}{2em}` to force this.

# Reaction to Bad Kerning

Methinks this is one syndrome likely to afflict LaTeX users as well as designers. Everyone who’ve felt this way whenever you see a badly kerned sign, say “Aye”!
