Tumblr has announced an upgrade of its attribution feature which will now only provide attribution to original sources within the post content, rather than all re-bloggers.

In the announcement on its staff blog, Tumblr says the upgrade was needed to fix issues within its automatic ‘via’ system, such as links being dropped, credit being buried under re-blog links, frequent mistaken attributions and the resulting impact on post appearance.

Starting today, reblogging will no longer insert attribution into the content/caption of the post except to quote content added by the parent post.

The new feature will also enable authors to attribute content to a source outside of Tumblr which will then be attributed whenever the post is reblogged on Tumblr, while the entire reblog history will remain in the post notes.
