How do you judge the quality of a journal? A colleague and I recently submitted a paper to a journal with an impressive-sounding name, the "International Journal of Artificial Intelligence and Computational Research". According to their website, 


  IJAICR is a referred [sic] journal in the field of computer science, artificial intelligence and soft computing methods.


It was accepted two days after we submitted it. That's too fast. We were suspicious. Although the journal said that all papers are peer-reviewed, we could not see how that was done in two days. Plus, we received no comments from the reviewers. Also, the submission guidelines didn't ask for a "blind" copy (without our names or any references to who we were). 

But wait, there's more.

The acceptance letter asked us to send them US$300 to publish it. We did not. We've withdrawn our submission and will submit a new version of the paper to a more reputable journal in the coming months.

How might we make a better choice of respectable journals before we submit next time?
The way I usually choose journals is by looking at where people I trust/follow publish, and where previous work was published. It is usually not too hard to compare the quality your work to the quality of the work you are citing, and chose a target based on that. Unless your field is highly mutli-disciplinary, you will see the same journals/conferences popping up again and again in your references; submit to one of those.

Before submitting, however, it is always important to look at a few articles from previous issues. This will give you a second gauge of quality for the journal and also let you pick up on any formatting and presentations quirks that might be present in the publication.
