Jason, You may want to allow people just to give you the robots.txt file which references the sitemap. I also register the sitemaps individually with the big search engines for our site, but I found that very large sitemaps aren't processed very well. So, for our site I think I limited the number of items per sitemap to 40,000. Which results in ten sitemaps for the digital objects and an additional sitemap for all the collections. http://ufdc.ufl.edu/robots.txt Or else perhaps give more boxes, so we can include all the sitemaps utilized in our systems. Cheers!

Sitemaps are the main mechanism for listing Web resources for automated crawlers [2]. Knowing about all of these various sitemaps could have many uses for research and improving the discoverability of digital collections on the open Web [3]. So I thought I'd put up a quick form to start collecting digital collections sitemaps. One required field for the sitemap itself. Please take a few seconds to add any digital collections sitemaps you know about--they don't necessarily have to be yours. https://docs.google.com/spreadsheet/viewform?formkey=dE1JMDRIcXJMSzJ0YVlRaWdtVnhLcmc6MQ#gid=0 At this point I'll make the data available to anyone that asks for it. Thank you, Jason [1] At least I don't recall seeing such a sitemap registry site or service. If you know of an existing registry of digital collections sitemaps, please let me know about it!
