+Track Record Merges
+^^^^^^^^^^^^^^^^^^^
+When 2 or more bib records are merged, all records involved are stamped
+with a new merge_date value. For any bib record, this field indicates
+the last time it was involved in a merge. At the same time, all
+subordinate records (i.e. those deleted as a product of the merge) are
+stamped with a merged_to value indicating which bib reord the source
+record was merged with.
+
+In the browser client bib record display, a warning alert now appears
+along the top of the page (below the Deleted alert) indicating when a
+record was used in a merge, when it was merged, and which record it was
+merge with, rendered as a link to the target record.
