In order to select a specific collection, go to https://familysearch.org/search/collection/list and use the "Filter by collection name" feature in the upper left-hand corner.
Each one of the collections listed above has a Research Wiki page (use the "Learn more" link). It would be very useful if the Wiki page for each collection listed the dates for when the collection was added as a new collection and the dates for major updates also.
UPDATED 22 December: used the FamilySearch email to determine ADDED or updated collections.
