Which subject holding should I choose for my site?

If your site covers several topics, choose the holding that best reflects its main focus. The General Reference Holdings section exists for sites that do not fit neatly elsewhere.

About the Colophon16 Index

Colophon16 is a structured catalogue of websites organised across 22 subject holdings. The directory currently indexes 830 approved entries, each assigned to a section and maintained as an active record. The catalogue follows an archival approach: entries are listed for reference, not ranked by commercial criteria. Sections range from specialist professional fields such as dental practice and legal services to broad general reference holdings covering arts, community, and miscellaneous resources. Colophon16 accepts submissions from site owners who wish their resource to be catalogued. Approved entries are assigned to the most appropriate section and made accessible to anyone consulting the directory.
