# The `longtwocolumn` LaTeX Package Providing `\longtwocolumn` similar to LaTeX's `\twocolumn` but allowing the optional argument to span several pages. ------------------------------------------------------------------------------ LaTeX package `longtwocolumn` Copyright (c) 2013—2025 Markus Kohm Release: 2025-07-21 v0.1 License: LPPL 1.3c (see [LICENSE](LICENSE.md)) CTAN Location: https://www.ctan.org/pkg/longtwocolumn ------------------------------------------------------------------------------ ## Summary `longtwocolumn` is the result of a question on komascript.de, which is no longer available. It provides a command `\longtwocolumn` similar to the LaTeX kernel command `\twocolumn`, but it allows the optional argument to span several pages. ## Status This is an early release of an experimental package. ## Installation We recommend to use the package manager of your TeX distribution to install packages. However, if you need to install `longtwocolumn` manually, you can either use a semi-manual installation or a completely manual installation. ### Semi-manual Installation For a semi-manual installation you can first create a local clone of the repository: ```bash git clone https://gitlab.com/latex9343737/packages/longtwocolumn.git ``` Then enter the directory created while cloning the repository: ```bash cd longtwocolumn ``` Last, but not least use `l3build` to install it locally with manual and sources: ```bash l3build install --full ``` or without manual and sources: ```bash l3build install ``` ### Completely Manual Installation To do a completely manual installation, download `longtwocolumn.dtx`. Then extract it using: ```bash tex longtwocolumn.dtx ``` To create the manual use: ```bash pdflatex longtwocolumn-example.tex pdflatex longtwocolumn.dtx mkindex longtwocolumn pdflatex longtwocolumn.dtx mkindex longtwocolumn pdflatex longtwocolumn.dtx ``` Now, you can either install it in the proper directory (see the documentation of your TeX distribution) or copy `longtwocolumn.sty` to your document directory. # How to Report Issues If you think you have found a bug (or another kind of issue) using `longtwocolumn` you should use [the issue tracker](https://gitlab.com/latex9343737/packages/longtwocolumn/-/issues).
