### Best LaTeX Resources on YouTube?

I've really enjoyed Michelle Krummel's LaTeX introduction on YouTube.

https://www.youtube.com/playlist?list=P ... 31D3EBC449

Now that I know that beginner-level stuff, though, I'm ready to move on.

Can anybody suggest a YouTube playlist to follow up with? There are so many videos there I don't know where to go next.

Thanks!

I picked one of the videos (the first on text formatting) and it started. My first thoughts were, you should never use those commands within the document. I skipped a bit and at minute four was cursing the video because what was told there is simply, excuse me, crap. Stuff like that promotes wrong bits and pieces that never stop floating around.

Nicola Talbot published some nice books for novices and advanced users, all of them reviewed by a large community of experienced LaTeX users. Please have a look at them, they are free. Dickimaw LaTeX books

btw: so, far, i haven't seen a single video on Youtube, that was 100 percent correct.
The smart way: Calm down and take a deep breath, read posts and provided links attentively, try to understand and ask if necessary.

What, exactly, was wrong with those videos?

Commands like textbf and friends shoudl never be used with in the body of a document. Better to use semantic markup and user-defined commands.

Font size switches are simple commands, using them as an environment is a wide spread misunderstanding, distributed over generations and more generations to come. The thing is, that the LaTeX ekrnel defines that stuff, that this still works. But i would never recommend that.

Unfortunately, Nicola introduces that as well. Gotta talk to her about that.

To be honest, I'm completely new to programming and LaTeX and didn't actually understand this message. What is "semantic markup"? I think (I know what user-defined commands are, though.)

Why is it so bad to use environments for font sizing?

textbf makes something bold, but there is no reason given. You are using semantic markup at different places, you issue the section command instead of changing to a bigger fontsize, stepping the section number by one, typesetting the text, make a note for the toc, switch back to normalfont and normalsize ...

All this is hidden, you can later decide that sections shall be bigger, or use another font and all instances of section will change.

Now, suppose you have latin names of plants species, you are setting them using textbf. Later you decide to change it to italics. You have to redo every instance, which might be ok for 5 occurences, but is highly impractical for 1000 occurences.

Following some source code, please cpy it into your favourite LaTeX editor and view source and pdf side by side. You can also click on »Open in Writelatex« (which is now overleaf) to see everything.


To put it in a nutshell, though placing the commands inuse of an environment with it working pretty well, there are situations where it terribly breaks down. Leaving an inexperienced user confused, looking for odd workarounds. That is why i am discouraging the use of commands as environments.

Please play around with the code above and ask if needed.
