, lynda.com, or General Assembly as a starting point. There are a lot of books available, but most of them focus on specific areas. UX is not UI, and understanding the different core areas is important. The same way Industrial Designers have skill sets in sketching, prototyping, 3D modeling, rendering (all very different areas and skills) UX includes: Information Architecture (content layout), User Flows, User Journey mapping, User Interface design, prototyping, wireframing, visual design, coding, etc. It is extremely rare for one person to be extremely proficient in all areas. I transitioned from ID into leading a UX team and focused more on the conceptual skills (IA, wireframing, prototyping) without focusing on the UI/Visual elements.
If you have access to local UX meetups that can also be a good venue. In general, UX is more accessible than ID - the software used can usually be found for free or very cheap (tools like Sketch or Invision are industry standards for building designs and quick mockups, but Illustrator and Photoshop work, even Powerpoint or Keynote can get the job done). Websites can be written in any free code editor. Because the barrier to entry is much lower (than say a $3,000 seat of Pro E) it's easy to play around with in your spare time.
Additionally, if you've been using a computer and smart phone, you're already up to date on modern UX standards. Download new apps to experience things you might not play with normally. There is a lot of cool stuff out there even if it isn't something you'll use everyday.
