When I refer to modern, I do not refer to modern theory, but of using an iPad/electronic device to look up articles and books, as well as PDF, while simultaneously using the Chess.com analysis board to follow, which is what I do to study chess. Often, I also follow books and lessons on an analysis board of my own, and also use Chess.com and the internet as a tool. 

Does anybody else study Chess this way? How are your study habits? Do you use an electronic device to substitute a few shelves' worth of books?

For me, not much compares to the pure enjoyment of studying from books.  I just love books.  

I used to use the analysis board along with the book study but I found that my OTB vision was not improving at all but my "online" game improved.   So, I got myself a nice set and board to study with so as not to get creamed when playing OTB. 

My study habits are basically to do as much tactics training here as I can.  Try to play a game or two per day (I know, not enough), and to try to get an hour of book/study time per day.  Wish I had more time available for chess.  Work, family, kung fu training/students all need my time.  

the video lectures really work for me.  they seem to stick well.  although i should spend an hour going over each standard game i play, i admit to scrolling through the moves with an engine until it jumps, letting me know where i lost or won the game and then studying that position for a bit. 

uhmmm, my thoughts,

having a book to have, and to hold is neat and sweet, having numerous PGN or PDF chess materials all in one folder stored in a notebook to carry along anywhere you go is super neat sweet

I use a great mixture of them. I use youtube mainly for openings, common traps, and historical games. Also I have books that teach you to think differently. I also take notation of my games to review them to see what I could have done differently.

Thanks for all your feedback. It's nice to note that in this era and time that almost anyone can go on Chess.com or go to the local library to learn about chess, and that much of Chess knowledge can be found free on the internet. But, they are not substitutes for books and OTB training. 

I use pdf format book together with fritz to study.
