The database used a colour-coding scheme to classify publishers according to their self-archiving policy. This shows authors whether the journal allows preprint or postprint archiving in their copyright transfer agreements. It currently holds records for over 22,000 journals. The colour codes were retired in 2020, with the launch of a new site.
