Selected links to armorials and heraldryRecently there has been an explosion of titles available on the web, which makes collections of links like this nearly obsolete. One might well try Google or similar search machines for any title or author wanted. Some 700 titles of books out of copyright can be found on www.archive.org and others on wikimedia or Google books.
For a fine introduction to blazon and heraldry try www.internationalheraldry.com. This website manages to present the key elements and well-chosen examples within a reasonably short space.
