MEDLINE/PubMed Baseline Repository (MBR)

The MEDLINE/PubMed Baseline Repository (MBR) provides access to each MEDLINE/PubMed Baseline snapshot starting with the 2002 MEDLINE Baseline. Each baseline contains a snapshot of MEDLINE citations in the state they were at a given moment in time without the MeSH vocabulary updates and other revisions that occur during the year. The baseline snapshot is created at the beginning of each new MeSH Indexing Year. The records included in the MEDLINE/PubMed Baseline databases represent a static view of the data at the time each baseline database was created.

MEDLINE/PubMed基准库（MBR）提供自2002年MEDLINE基准以来的每个MEDLINE/PubMed基准快照的访问权限。每个基准均包含MEDLINE引文在特定时间点的状态快照，该快照未包含年内发生的MeSH词汇更新及其他修订。基准快照在新的MeSH索引年度之初创建。包含在MEDLINE/PubMed基准数据库中的记录代表在创建每个基准数据库时数据的静态视图。
