What is LaTeX?
LaTeX (pronounced /lay-tech/) is document preparation system that allows markup to describe the structure of a document so that the user do not need to worry about the presentation of the document. By using document classes and add-on packages, the same document can be produced in a variety of different layouts.
What are the advantages of using LaTeX?
Commonly used by scientists, engineers, mathematicians and other professionals, LaTeX is the de facto standard for the communication and publication of scientific documents. Unlike a traditional “what you see is what you get” (WYSIWYG) word processor (e.g. MS Word processor), LaTeX uses a plain text markup language which is compiled into a PDF document using optimal typographical rules.
In particular, it includes features designed for the production of technical and scientific documentation. This results in professional-looking documents that are of a different class to the output from a word processor. The numerous customization options in LaTeX allow for the creation of a diversity of documents with precise control over layout and formatting.
Is it difficult to learn LaTeX from scratch?
The answer is no, and you don't need to start from zero either. There are many readily available templates which do not require your advanced knowledge of LaTeX to use. You can use the templates available to create beautiful documents and learn to customize/create your own LaTeX file as you learn more about it.
What is TeX?
TeX is a file extension for a LaTeX file format.
What is BibTeX?
BibTeX is a program that works with LaTeX for including in-text citations and reference list in your LaTex document. Many reference managers offer some level of support for working with LaTeX and BibTex. For example, Mendeley can automatically generate LaTex Citation Command and BibTeX entry for the reference that you select.
LaTex is available as free software, you can get LaTeX for Linux, Mac OS X, Windows. In addition, there are also a number of online platforms that allow you to create LaTeX files directly online without installation.
Linux - TeX Live
Mac OS - MacTeX
Links to the major LaTeX software and online platforms can also be found in the LaTeX Official Website.
There is also a TeX document preparation package created in the Chinese language environment called CTeX which you can install.
LaTeX is a powerful tool to typeset math formula and equations. It is possible to typeset integrals, fractions..you name it!
For example, the LaTeX code:
And the output is:
You can generate equations/formulas into LaTeX codes using a number of online available tools. To list a few:
Writing a paper in LaTeX format is a fun troubleshooting process. You will encounter lots of technical challenges (almost guaranteed!), but in the meanwhile, you pick up the tricks gradually and you will be able to learn faster and faster. Therefore, do not feel frustrated at the beginning of using LaTeX!
Many LaTeX experts, discussion forums, and communities usually have readily available references and answers to your questions. When in doubt, type in your questions in Google and normally you can find something useful.
Here are some sites that can be useful for your self-teaching as a beginner:
In addition, the library also has a number of books on LaTeX:
What is BibTeX?
As briefly introduced above, BibTex works with LaTeX to allow you include citations into your document. The word BibTeX stands for a tool and a file format which is used to describe and process lists of references, mostly in conjunction with LaTeX documents.
What is the format of BibTeX?
A BibTeX entry consists of the type (the word after @), a citation-key and a number of tags which define various characteristics of the specific BibTeX entry. For example, here we have a book "The Image Processing Handbook, Seventh Edition" by John Russ. The BibTeX record is:
@book indicates that this reference is a book. The citation key (aka citation command) is Russ2016 (you can also come up with other expressions/strings as the citation key). And there are a number of tags, such as author, isbn, pages, title, describing different aspects of this reference.
How does BibTeX work in LaTeX?
In short, you need to have two files ready: .bib file (which is essentially a plain text file) and your LaTeX file (.tex format).
In you BibTeX file, there should be a list of BibTeX entries, for example:
Then, in your LaTeX file, you need to indicate that you are using the cite package, and insert necessary citation commands, and then indicate the bibliography file name, bibliography style.
How does Mendeley help with generating BibTeX entry?
Mendeley can generate LaTeX citation command and BibTeX entry for the reference selected.
Take the record (screenshot) as an example, the automatically generated command is:
And the BibTeX record is:
Quite simple isn't it? With the two components ready, you can insert the LaTeX command into your ".TeX" file and copy-paste the BibTeX entry into the .bib file where contains all the cited reference in your LateX project.
Rather than copying & pasting, you can also export the selected reference to a BibTeX (.bib) file. To do so, first select references that you would like to export to BibTeX, then click "File –> Export" and in the dropdown list of file types, chose "BibTeX (*.bib)" and save it to your drive.
