The idea of a first reading list for anyone coming into library linked-data work is not realistic, for obvious reasons. We all show up with different backgrounds, skill sets, and learning styles, and this means that we’ll find different resources more and less helpful. For this reason I should say a little bit about my background as it relates to library linked-data work.
When I started my MLIS program I had no real programming experience. I did have an interest in computing, and maybe because of this, I found myself focusing on digital collections and digital preservation fairly early on. This put me in a challenging spot–I felt I had some catching up to do in terms of technical skills. I began to gain these through coursework and hands-on learning, but these things take time, and the process is ongoing. My approach to linked-data work–and this reading list–have been shaped by the fact that I’m a relative beginner.
Also, I selected from items I’ve already read to create this (very short) list, and I haven’t read everything on the subject! I hope to hear back from readers willing to share their experiences with resources not included here.
