I work on the supply chain, capital expenditure team at an electric car company and I can tell you none of the books listed below will help you. Get an internship or offer to work for someone for free. Supply Chain Management is one of those things that is best learned on the job. You need to 'learn' your supply base/ vendors who do good work, you need to learn how to negotiate things like payment terms instead of just price, how to effectively track you 100+ things you need to buy that day. All the books listed below are great if you are a factory production manager, but will never help you in an entry level supply chain job.
I suppose whether or not these books apply depends a lot on where my life takes me. But you are right about the concrete practice, just like with learning a new programming language, the only way to internalize it is to do a project with it that preferably has a real pressure and deadline, i.e. a job.
I'll have to see if I can try and apply the concepts no matter what industry I'm in.
