Whether you’re making an application or a web design, it’s useful to have a collection of high quality icons handy. Your users will appreciate the professional touch and ease of navigation that they bring. Over the years I’ve collected a ton of sets, I spent a couple hours digging through them all and compiling this. All downloads are hosted on my server in their original unaltered archives and include a mirror to the author’s website if applicable, this is a proactive measure in case their sites ever disappear.
