I have two papers published in a APS journal and another paper just got accepted to the same journal (the journal is a reputed one in my field). It has been almost two years for my PhD. So I have started drafting my next research outcome. My plan was to try another journal this time. However, my supervisor is suggesting me to submit to the same journal. If in case this journal's reputation goes down (however, this is very unlikely), all my work kinda get wasted. On the otherhand, is it good to have all PhD papers in one journal (It might look like I cannot reach scopes of other journals)? Thanks in advance.
Welcome to [email protected], @QuantumGirl. It might differ (slightly) between fields, but in general, I'd say it is not good. Journals have different readerships, and you want to reach different audiences. Next to that, you want to avoid the impression that you are a one-trick-pony with research that is so narrow that it is only publishable in one specific journal (again, not knowing the specific circumstances in your field of course). But in general, a bit of diversification to me sounds a much better strategy, even if it is a good journal.
