How can I learn advanced LaTeX and become a full LaTeX programmer?
Here's a (possibly opinionated!
:-) ) list of books/resources that might be helpful:
- Check out the third part of our online interactive LaTeX course
- The LaTeX wikibook covers quite a bit of advanced stuff, including lower-level topics like lengths, boxes, macros, creating packages, etc.
- Stefan Kottwitz's LaTeX Cookbook is nicely structured, with a lot of good examples.
- The classic LaTeX Companion is still a classic, in our opinion.
- Nicola Talbot's new book LaTeX for Administrative Work is a lot of fun -- automating many tasks with LaTeX.
- No LaTeX book list is complete without The TeX Book and TeX by Topic, especially if you're interested in the actual working details of TeX and LaTeX
- Take a look at this TeX.SX question for more inspiration!
Also, hanging around on TeX.SX to browse and answer questions would also help gain quite a bit of experience. You can also follow Overleaf's twitter feed about our Gallery updates for interesting examples.
