medrxivr: Access and Search MedRxiv and BioRxiv Preprint Data
An increasingly important source of health-related bibliographic
content are preprints - preliminary versions of research articles that have
yet to undergo peer review. The two preprint repositories most relevant to
health-related sciences are medRxiv <https://www.medrxiv.org/> and
bioRxiv, both of which are operated by the Cold
Spring Harbor Laboratory. 'medrxivr' provides programmatic access to the
'Cold Spring Harbour Laboratory (CSHL)' API <https://api.biorxiv.org/>,
allowing users to easily download medRxiv and bioRxiv preprint metadata
(e.g. title, abstract, publication date, author list, etc) into R.
'medrxivr' also provides functions to search the downloaded preprint records
using regular expressions and Boolean logic, as well as helper functions
that allow users to export their search results to a .BIB file for easy
import to a reference manager and to download the full-text PDFs of
preprints matching their search criteria.
