NOTE: You don't need to record the author's main points. You need to record what about each resource matters to your topic and how it fits within the CONTEXT of other sources.
Here's an example from my research.
NOTE: I came up with the themes based on skimming multiple articles. These are not the main themes of the particular article. The middle column is meant so you do not have to go back to the original article and hunt for concepts & quotes. Be sparing in your use of quotes when you write your paper, but feel free to grab quotes now if you want. The third column is so that you do not go down a rabbit hole. Stick with this step of reading each article before moving to the next steps. Write down that you found a new source in the bibliography, or a new term, but don't go find more articles yet. Finish reading the ones you already found first!
Another helpful text for those working on dissertation or thesis:
Filter your sources easily based on the themes you found above.
Helps with writing later!
Use few words (yes or no) so easier to sort
