BIOC35: Principles in Parasitology

This guide will help students in BIOC35 find articles, know the types of sources and how to evaluate them, and develop effective readings strategies of scientific articles.

Key Resource


bioRxiv is pronounced "bio-archive". It is a free online archive and distribution service for unpublished preprints in the life sciences that is operated by Cold Spring Harbor Laboratory, a not-for-profit research and educational institution.

Articles are not peer-reviewed, edited, or typeset before being posted online.

Pros & Cons

Pros Cons
Access it easily: no paywalls, which means wider dissemination  Perception of low quality: lots of eyes on the research for informal feedback and can still be peer-reviewed in the future
Record of Posting Date: permanent datestamp  Risk of invalid findings: the informal feedback of preprints is meant to capture issues prior to publishing. However preprints risks disseminating errors to the public before being formally vetted. 
May still publish in future: Check SHERPA/RoMEO for specific journal preprint policies Risk of embargo violations: If preprints do end up getting published in media it can be considered prior publication.  
Established work: Good for early career researchers; funders like NIH accept preprints   
Rapid evaluation of article: researchers have access to feedback mechanisms to help improve research for publication
