* Citation Machine: http://citationmachine.net/ The information involved in a citation comes from a database. Hence, if there is no information in the database, you must use manual entry. Citation Machine just simply gets the format, plugs in the information, and then displays it for you to copy and paste. Citation Machine uses ISBN numbers to query their database, the authors have not, as of yet, found an ISBN number which exists in the Citation Machine database.<br> * Xpert: http://www.nottingham.ac.uk/xpert/attribution/ This site also uses a database. However, they explicitly offer the usage of their current database, which means they might also offer knowledge on how they've created the attibution information on individual resources.  * CC Metadata Humanizer: http://code.creativecommons.org/~john/ * OCW cite/attribute: http://ocw.korea.edu/ocw* Wikimedia Commons: http://commons.wikimedia.org* Wikipedia citation tools: http://en.wikipedia.org/wiki/Wikipedia:Citation_tools
