I archive all my reading notes in a blog linked from the website. However, as good as it is as a web diary, the organization of articles in a blog is not entirely satisfactory. Articles are arranged in chronological order. I have been looking for a way to categorize, sort and search articles but still cannot find a good solution. At last, I created an index myself sorting articles by category. It is now a webpage in my website. For those who want to read my blog of reading notes, I suggest you enter from the icon of Reading Notes in the homepage to see the index first.
