Check your sources.

Find issues and concerns with an article’s sources to the 3rd generation.

RedacTek’s generational source validation services include:

  • Retraction notifications - We note when an article or source has been retracted, across three generations of sources (available now).
  • Browser Plugins – Starting with Chrome, we’re making browser plug-ins that will allow you to see RedacTek alerts for articles based on the DOI/PMID that appears on a browser page (available now).
  • Author self-cites – When an author cites their own work as more than 25% of the sources for a given article, care should be taken to ensure there is a good reason to so exclusively rely on their own previous research to ensure nothing unethical has taken place (just implemented).
  • Crossref Data – Crossref allows for a fuller compliment of reference sources, along with a more complete store of DOI and PMID numbers (2022).
  • PubPeer Comments – This is where post-publication peer discussion takes place, which can help identify scientific concerns with a source prior to that source being retracted (2022).
  • Predatory Journals - Partnering with Cabell's, we identify articles and sources published by predatory journals, who do not properly conduct peer-review of their publications (2022).
