	### Dataset Summary

	PubMed comprises more than 36 million citations for biomedical literature from MEDLINE, life science journals, and online books. Citations may include links to full-text content from PubMed Central and publisher web sites.

	NLM produces a baseline set of PubMed citation records in XML format for download on an annual basis. The annual baseline is released in December of each year.
	- Last Updated December 15, 2023

	Each day, NLM produces update files that include new, revised, and deleted citations.

	## Dataset Structure

	Bear in mind the data comes from XML that have various tags that are hard to reflect
	in a concise JSON format. Tags and list are kind of non "natural" to XML documents
	leading this library to make some choices regarding data. "Journal" info was dropped
	altogether as it would have led to many fields being empty all the time.

	The hierarchy is also a bit unnatural but the choice was made to keep as close as
	possible to the original data for future releases that may change schema from NLM's side.

	Author has been kept and contains either "ForeName", "LastName", "Initials", or "CollectiveName".
	(All the fields will be present all the time, but only some will be filled)

	## Dataset Creation

	### Curation Rationale

	The use of "Medline" in an element name does not mean the record represents a citation from a MEDLINE-selected journal. When the NLM DTDs and XML elements were first created, MEDLINE records were the only data exported. Now NLM exports citations other than MEDLINE records. To minimize unnecessary disruption to users of the data, NLM has retained the original element names (e.g., MedlineCitation, MedlineJournalInfo, MedlineTA).

	Policies affecting data creation have evolved over the years. Some PubMed records are added or revised well after the cited article was first published. In these cases, on occasion an element that had not yet been created when the article was published may appear on the record. For example, the Abstract element was not created until 1975, but some records published before 1975 but added to PubMed after 1975 contain <Abstract>. It is also possible that an element may be treated differently from the way it would have been treated had the record been created or maintained near the time the article was published. For example, the number of <Author> occurrences can diverge from the policies stated in the NLM author indexing policy (https://pubmed.ncbi.nlm.nih.gov/help/#author-indexing-policy). Lastly, as of October 2016, the publisher of the original article has the capability to edit the PubMed record’s citation data, with the exception of MeSH data, using the PubMed Data Management system. PubMed record data for older citations, therefore, may contain data for elements that didn’t exist when the citation was created.
