Romantic, you should just find Tal's life and games, or Morphy. Morphy is theoretically the best, since he comes from the period. Tal just found tactical solutions to positional problems.
Classical: Books by Tarrasch
Hypermodern: My System by Nimzowitch.
Another great idea is to create a list on all the world championsships from 1886 to around 1950, and then find all the games annotated. There is probably alot on the internet. It will give a great understanding of the old champions.
Romantic: 1. Life and Games of Mikail Tal and 2. Fire on Board. For fans of romantic or attacking chess.
Paul Morphy and the Evolution of Chess Theory by Mcaon Shibut. Great analysis, text, articles, and every known game of Morphy. Two books I highly recommend that cover a lot of the critical ideas of all three styles (with outstanding examples) are The Giants of Chess Strategy and The Giants of Power Play, both by Neil McDonald. Very well written and presented. When you get to around 1700-1800 you'll want to read Tactics for Advanced Players by Yuri Averbach, one of the best books I ever read. Hope this helps.
what are some good books in algebreic notation in each catagory. i kinda want to start from the beginning (romantic)to get a complete understanding and then move on to see how it evolved (classical). my rating on here averages 1500 so i dont think i need any beginner books. i have pawn structure chess by soltis, chess fundamentals by capablanca and winning chess tactics by seirwann.
