IV. Recommended Materials

Since HTML is so simple, any good book will be sufficient (most HTML books should be mature by now, if they are still in the market).

• Ian Graham,. "HTML 4.0 Sourcebooks," John Wiley & Sons, ISBN: 0471257249: I learnt HTML using an earlier version of the book many years ago.
