What are the date ranges for past MeSH Indexing years?

The table below contains the date range for each MeSH Indexing year as applied to completed MEDLINE citations. Once a year, generally in mid-November, all MeSH headings on citations are synchronized with the new edition of MeSH. The MeSH Indexing year runs until the next global update of citations. To retrieve all of the MEDLINE/PubMed citations for a specific MeSH Indexing year, search for the date range for the MeSH Indexing year followed by the Date Completed field tag [dcom].
