Greetings, Our Library is putting Finding Aids on the Web. We're including a link to the online catalog record of the collection each finding aid is for. We aren't sure of the best place to put this reference and I didn't find any similar examples on EAD sites. Here's one option we have considered: <archdesc level="collection" type="register"> <did> <unittitle>COLLECTION NAME</unittitle> <physloc>Click here for the catalog record and location information:<extptr href="http://link_to_catalog_record"/></physloc> </did> All suggestions and help are appreciated.
