Pdfminer is a python package to convert pdf to text and other formats. Pdfminer is not actively maintained. There's a similar package name pdfminer.six that is community maintained. Check out https://pypi.org/project/pdfminer/, https://github.com/euske/pdfminer, https://github.com/pdfminer/pdfminer.six, https://pdfminersix.readthedocs.io/en/latest/index.html

pdfminer.six and pdfminer gives the same result for conversion to text for "arp4655.pdf". There are several texts in "Reference" section that is missing. Attached is the text output. arp4655.txt

Both grobid and pdfminer was compared for several pdf files and results shared in Box folder (RCT-Transparency > pdf manuscripts > grobid-pdf-extractor and pdfminer-pdf-extractor) on June 6th. After discussions, neither one proved better than the other.. However, only a small sample of pdf files were tested.

Decided to stick with Grobid.
