A lovely little, and useful, publication covering the basics of typography from Adobe. It was actually first published waaaay back in the day, circa 2000, but the contents are still very relevant over a decade later.
From Adobe’s blog post: “This primer was written back in 2000, but its content is still relevant today. It talks about things like using the right character, choosing and using typefaces, combining typefaces in a publication, and loads of other interesting typographic tidbits. If you follow our blog, you probably already know a lot about type. If that’s the case, why not take a look inside anyway? Think of it as a fun refresher when you need a break from work. Perhaps it’s even something you might share with a co-worker who longs to know more about the mysterious world of x-heights and optical sizes.”
