I'll either write quotes from a book by hand or type it out on some word processor. But there are times I've typed out or written out entire chapters from a book. And one book I almost transcribed pretty much from end to end.

I think it's pretty inefficient. And I definitely don't recall perfectly. But it does help a lot of the info lodge in deeper than just active reading. Might just be a belief I hold, and I don't really recommend others to do it because it's definitely a lil kooky and time consuming.
