The entryway of the central branch of the Brooklyn Public Library.

The Brooklyn Public Library gives all of its patrons free access to Lynda.com. The site is a repository of web videos organized into courses where you can learn all kinds of skills. Access to their catalog of courses usually costs $25 per month, but with your library card you can get in for free.
So let’s say you want to launch a startup and have absolutely no skills of any kind: here are some topics you could start learning about at home, through your web browser, thanks to your membership at the library:
Code and web dev

Design

Business development

There are vastly more videos on there and these are just a few that struck us as useful for getting started, but have a look. They have courses covering all sorts of topics. The fastest way to figure out what else you need to learn is to start learning something and see if it fits. If learning from home works for you, the link at the top of the page could save you $25 every month.
