Websites come and go but these have been up for years but still check Google for newer ones, videos, etc.
A fantastic site with lots of photos illustrating what is discussed is A Tourist in Rome [I couldn't help but add that one myself -Jeff]
penelope.uchicago.edu/Thayer/E/Roman/home.html [This is *THE* website to learn *everything possible* about Rome and the Roman Empire. Just scroll down the homepage just to see all it offers but if you have a specific thing you are searching for just scroll down to the bottom of the page and use the 'Search this site' 'search engine'.]
penelope.uchicago.edu/Thayer/E/Gazetteer/Places/Europe/Italy/Lazio/Roma/Rome/_Texts/PLATOP*/home*.html. Use the links in the 'General Topic Areas'. This site is very good for historical and archaeological info. The info is from material published about 75 - 125 years ago and for the most part it is very accurate but any new discoveries or historical revisions wouldn't be included.
Another good site is: legacy.fordham.edu/halsall/ancient/asbook09.asp
If I had to recommend one book to go along with this walking tour of the Roman Forum it would be
Suetonius' 'The Lives of the Twelve Caesars'.
It covers the era from Julius Caesar (born about 100 BC) to Emperor Domitian's assassination in 96 AD.
Also here: legacy.fordham.edu/halsall/ancient/suetonius-index.asp
For a modern easier read with the author's excellent narrative and explanations read Michael Grant's 'The Twelve Caesars'.
