In the last couple of days I’ve been reading the book Practical Typography by Matthew Butterick. It’s a free online ebook I read about on Hacker News some months ago, but I didn’t read it seriously until now.
I think it’s a great book that can help anyone create better documents, offline or online, and I highly recommend it. It’s full of insight into the world of typography and contains lots of great advice. It made me send Butterick $10 as per point 6 of the “How to pay for this book” section and now I’m contributing on point 7. :-)
Update: I forgot to mention the book made me rediscover two very nice fonts for those of us who are short on typography budget. Bitstream Charter, which is commonly found in many Linux distributions, is a very nice serif font. Butterick has also put together a packaged ZIP file to ease distributing and installing the font to other platforms. I’m also redistributing a copy from here. Also, Source Sans Pro is a very nice sans serif free font from Adobe that was published for the first time in 2012.
