Why am I seeing multiple entries with different coverage dates in a WorldCat knowledge base collection?

Answer
Generally, if you see a title represented twice in a collection with different coverage ranges, it is to denote gaps in coverage for a title. The same OCLC Entry ID must be used for each instance of the title's coverage to associate it with the same title.
However, adding multiple coverage dates as rows in a KBART file for the same item AND using different entry IDs (oclc_entry_id ) will create duplicate titles when that KBART is loaded into a collection. Please report this to OCLC Support for correction.
