I’ll be adding to this list, so please let me know if you have any WordPress resources you think should be added here. For those of you who want to understand WordPress PHP better, be sure to check out: http://adambrown.info/b/widgets/easy-php-tutorial-for-wordpress-users/

WordPress Books

• The CSS Anthology: 101 Essential Tips, Tricks & Hacks, 3rd Edition – While there are many wonderful online CSS resources, this book was an exceedingly helpful resource when I was getting started to give me quick access to common CSS tips and tricks.
• Digging Into WordPress – I love this book but also recommend it with some reservations as many of the recommended plugins are outdated and the code examples are out of context or not applicable to the context in which they are set. I would get Professional WordPress first and use this book for its other helpful tips.
• WordPress Theme Design – Very helpful for theme developers but a bit more complicated than it needs to be. I prefer to “tweak” an existing simple theme than go through the developing every bit of a theme from scratch as suggested in this book. However, the examples he provides and overview of theme pages and parts is very helfpul.
• WordPress for Dummies – A must read for newbies. The section on theme development is very helpful.
• Professional WordPress – For advanced users, this book really helps to take your theme customization skills to a whole new level. The custom query chapter has many helpful code examples, all of which work!
• WordPress Plugin Development – I haven’t read this yet, but it looks awesome. I can’t wait to check it out.
• NEW!!!! WordPress All in One for Dummies – 8 books in 1. This 800+ page brick of a book covers all the basic of WordPress as well as SEO, how to create your own plugins, how to set up multi-site, and more!

WordPress Tutorials

• http://wordpress.tv/ – Free online video tutorials. Be careful because many of these are geared toward wordpress.com rather than toward self-hosted WordPress sites.
• http://lynda.com – Lynda has great tutorials on CSS, HTML, and WordPress. Well worth the $25/month subscription to continue your education.
• http://adambrown.info/b/widgets/easy-php-tutorial-for-wordpress-users/ – I love this free tutorial because it helps coders who are not PHP programmers (and programmers new to WordPress) understand the various PHP code snippets used in a typical theme.
• http://www.latestwp.com/ – Latest WordPress news, themes, and tutorials

WordPress Themes

• This post contains links to some simple themes that I think may be a good starting point for theme customizations or for just having a Zen-like site: http://askwpgirl.com/simple-minimal-wordpress-themes/
