There are a number of ways to get google and other search engines to only crawl what you want them to crawl. 1) You can create a robots.txt file that dictates directories or URL patterns that the robots should not crawl 2) You can add a tag to your HTML header that reads <meta name="robots" content="noindex"> (basically - robot you cannot index this page) 3) Create an XML sitemap for your site. I believe this is the best option for what is being discussed here. It is basically a laundry list of all the URLs you want google to crawl. See more here about the format: http://www.sitemaps.org/protocol.php . You would then create a Google Webmaster Tools account for your domain and submit your sitemap to them. Google can definitely crawl dynamic pages and while you will usually do better for SEO with a static URL that doesn't have a gillion parameters hanging off the end, don't let that URL format make you think you can't be included well in the search indexes. Also - it is my understanding that google will stagger the crawling of your site when it is first pulling content into the index. It is smart enough to watch for the rhythm of your updates so it figures out over time how often it needs to recrawl your pages. For most finding aids and other collection descriptions, your page won't need to be recrawled more than once in a blue moon. Part of what you tell search engines in your sitemap file is when a URL was last updated. I will be chairing a session at DC 2010 on SEO for archives websites and I will make sure that I post back to this list with links to the presentations and any reference sheets we develop.
