NOTES ON USE OF THIS FORM

• In all the text boxes you can use * & ? (or % and _) as wildcards within terms e.g. Ark*ales 197?
• It would be possible to give results in different formats if users would like this (i.e. to have extra options beyond citations and images). Suggestions welcome!
• There is also a separate page giving more information on the tags and metrics.
