Poor formatting, incorrect language, or wrong contents?
Fig 2.
(A) Terminology to describe the “anatomy” of glyphs. (B, C) Samples of serif (B) and sans serif fonts (C), all of them nominally of the same size (but notice the differences in width, x versus ascender/descender height and overall apparent size). (D) Confusing use of fonts for a purpose they were not designed for.
Fig 3.
(A) Typographically correct symbols make a difference between sloppily written and conveniently readable texts. (B) Many language use the Latin alphabet combined with different types of diacritics and additional characters.
Fig 4.
(A) Left-aligned text randomly emphasizes words appearing at the end of the line (indicated in orange); right-aligned text makes finding the next line unnecessarily difficult for the readers (indicated in blue); centered text combines both disadvantages; and justified text avoids these issues and has the calmest appearance. (B) Examples where hyphenation or line breaks interrupt the flow of reading (hyphenation examples from p. 115 in [30]). (C) Indenting the first line of paragraphs (except after headings) clearly indicates where a new paragraph starts, and this may be unclear at the top of a page otherwise.
Fig 5.
(A) Text in italics, small caps, or a matching alternative font does not change the type color of the page and emphasizes words within the context while reading. Bold text, uppercase letters, and different colors are more prominent and serve as “entry points” to the text. Using a contrasting alternative font, letter spacing, and underlining words forms an even stronger visual contrast, but is challenging to get looking good. (B) In the era of typewriters, authors were much more limited in using emphasis in their texts. (C) Italic, bold, and small caps should be used as properly designed font variants and not be faked by slanting (making the text look unnatural), making lines thicker (leading to, e.g., shrunken eyes and unbalanced spacing), or scaling capitals (making glyphs skinny). (Disclosure of image manipulation: text typed using a mechanical typewriter was digitized and edited for clarity, and color channels of the RGB image were manipulated to imitate red text from a 2-color ink ribbon).
Fig 6.
(A) One way to construct page margins for 1-sided and 2-sided layouts, also considering the type of binding used (here: spiral binding with narrower inner margin—glue or sewn binding requires enlarging the inner margin). (B) Figures (or tables) are commonly placed at the top of a page (or on figure-only pages), but not in between the text. (C) Orphans and widows, single lines of text separated from the rest of their paragraph, should be avoided.
Fig 7.
(A) Hard-to-recognize list, (B) properly formatted unsorted list, and (C) properly formatted numbered list.
Fig 8.
(A) Poor-quality plot: numbers are hard to read, symbols are not displayed properly, and color provides no additional information (except that automatic spell checking marked part of the axis labels as wrong). (B) Same data, better plot quality. (C) Poor-quality table: excessive lines and hard-to-read numbers, even in the right-aligned column due to the footnote symbol and numerals of different width. (D) Same information, better table layout.
Fig 9.
(A versus B) Formulas in the text should use a font matching the text and match the baseline of the text. Mathematical variables should be typeset in italic, unlike text parts of formulas or certain functions. (C versus D) Similarly, displayed formulas should match the surrounding text and are easier to understand if properly aligned. (E) Chemical formulas include subscript and superscript indices around symbols for chemical elements.
Fig 10.
(A versus B) Marking headings as the appropriate level of headings (instead of manually formatting it bold and larger) ensures consistent layout (Google Docs example). (C) Using automatically numbered headings and proper cross-references (rather than manually entering it) allows keeping them up to date automatically (Microsoft Word example). (D) Using a macro name indicating its purpose (rather than having to remember the formatting for a specific purpose) makes writing easier (LaTeX example).
