enter image description here I am editing a book and I want each page to contain two columns, one larger and one smaller, as it appears in the example, so that when you print it you can fill it without any problem. If I use minipage the construction becomes very difficult to work since it is a book.

  • From your screenshot it seems that you may also want to synchronize these columns. Therefore, I am wondering if you are aware of the paracol package, which allows you to assign the columns different widths by saying, e.g., \columnratio{0.6}. – user121799 Nov 16 '18 at 2:45
  • @marmot The following message appears when I give you the paracol package. "File `paracol.sty' not found." – Samuel Diaz Nov 16 '18 at 3:19
  • It is part of the standard TeX installations and can be found here. – user121799 Nov 16 '18 at 3:23
  • I would go with a one-column text and put the figures and notes in the margin instead of creating a smaller column for that. I always tought LaTeX wasn’t made for handling layouts like this. – Tommiie Nov 16 '18 at 3:40

Here I illustrate what one can do with paracol. Note, however, that I am not implying that the way I design the headings is the way to go. Rather, you might use titlesec in order to design sections, subsections and so on. However, I'd like to separate these things and therefore like to ask you to ask a separate question on this if you have problems carrying this out.

The purpose of this answer is just to say that judging from your screenshot paracol might be worthwhile being employed. This MWE is supposed to illustrate this.

It does have two separate columns of different widths, which are however synchronized in a way that may make it straightforward to produce something along the lines of your screenshot (which I actually like).

  • Thank you but the message continues to appear "File `paracol.sty' not found. \usepackage" when I give you the document. I will rephrase the question as you advised me. – Samuel Diaz Nov 16 '18 at 3:49
