I'll start by stating that this website is not for the beginner learner, simply because the works published there are intended for more academic purposes, however, it can still be useful for some of the very obscure papers that are available there if you want an in-depth analysis.
- Rich variety of papers allows for the possibility of some truly incredible subjects ('Avar Grammar Sketch', anyone?)
- Free option, with registration, means enough access to be able to view and download papers.
- Can be quite intimidating to manoeuvre through if you do not know exactly what you're looking for.
- If you haven't upgraded to the premium, you'll have to click through multiple windows just to access the singular paper you want.
Overall though, absolutely a great resource, and definitely worth checking out; you never know what will pique your interest! Cheers.
