Reddit reviews Post-it Tabs, 2 inch Solid, Assorted Primary Colors, 6/Color, 4 Colors, 24/Pk (686-ALYR)

Here they are, (or at least these are similar). I bought these for school and somehow never used them. Might try to implement them in my bujo now!

First off, in my view, a book of that type needs to be read at least twice, and you can take a different approach with each reading. My go-to method is to use highlighters (sometimes different colours) as well as Post-it Tabs - big and small (or generic brand name). Here are, for example, big ones: http://amzn.com/B004I7HHSO
[By the way you can easily write on these with Magic Marker to label].
And here are smaller ones: http://amzn.com/B003IJXJFS

You can use the bigger ones to mark chapters and/or sections, and use the smaller ones for chapter summaries, or for places where important techniques / practices / processes or principles are described. The second time I read, I use underlining with pen (or just highlighting again) to bring out points missed last time. Finally, I use Evernote and copy usually just from those parts that were underlined/highlighted (but I can still be selective here, adding or omitting important points whether highlighted or not). Later, you can just read the highlighted parts in the book, or review your Evernote notes.

Additional suggestions:

1. If you can find interviews with the author, especially when they were promoting the book, this can really give you an encapsulated précis and help you hear the author's voice later on as you read, which I think can help smoothen out the reading process; of course, YMMV
   
   
2. Amazon reviews, esp. some of the longer ones, can be useful in summarizing the main points and to give you a map of the book's contents.

I use these. All my records are in plastic sleeves and organized by artist and then I have one section specifically for soundtracks.
