I want to read the Notebooks, but there are 1,565 pages and I have too much else to read.
At a page a day it would take a little over four years, but be manageable.
Fortunately Project Gutenberg (who make freely available online out-of-copyright books) has created a text version of the Notebooks of Leonardo Da Vinci. You can download it. It lacks the illustrations of the original, but it's Good Enough.
Using this site, I can read one page a day using my RSS News Reader. Find an RSS News Reader. I started at page 1 on May 30th, 2004. I'm now on page 5349. You can either read along with me, or start reading at page 1 today.
Subscribe to one of the following two feeds (copy and paste the URL into your Reader):
→ Start reading today (starts at page 1): http://interconnected.org/home/more/davinci/2019-01-20.rss
→ Read with me (starts at page 5349): http://interconnected.org/home/more/davinci/2004-05-30.rss
Whichever feed you choose, the fifteen most recent pages are shown (so you can get a little behind and still catch up).
