Beall's list

*The service is offline*

"Beall's List", a website by Jeffrey Beall, includes criteria for categorizing predatory journals and lists publishers that meet those criteria.

Predatory publishers provide limited publishing services while pretending a much higher standard and reputation than they actually have. When publishing in a journal for the first time, ask yourself:

  1. Is the journal or publisher listed in Beall’s List?
  2. If claiming to be an open access journal, is the journal in the DOAJ?
  3. Is the publisher a member of recognized professional organizations?
  4. Is the journal truly indexed?
  5. Is the journal transparent and following best practices in editorial and peer review processes, governance, and ownership?

Information on why Beall's list disappeared can be found in the web or here.

Google Translate

The free online translation service from Google translates text and web pages in seconds and from 71 languages

When Google Translate generates a translation, it looks for patterns in hundreds of millions of documents to help decide on the best translation for you. By detecting patterns in documents that have already been translated by human translators, Google Translate can make intelligent guesses as to what an appropriate translation should be. This process of seeking patterns in large amounts of text is called "statistical machine translation". Since the translations are generated by machines, not all translations will be perfect. The more human-translated documents that Google Translate can analyse in a specific language, the better the translation quality will be. This is why translation accuracy will sometimes vary across languages.
