“Hipster” overlay journals

Been thinking a lot about overlay journals and their implications these days. For those who don’t know, an overlay journal is sort of like a “meta-journal” in that it doesn’t formally publish its own papers. Rather, it provides links to other preprints/papers that it thinks are interesting. On some level, the idea is that the true value of a journal is to serve as a filter for what someone thinks is science worth reading so that you don’t have to read every single paper. An overlay journal provides that filter function without the need for the rest of the (costly) trappings of a journal, like peer review and, uhh, color figures ;). 

There is one very interesting aspect of an overlay journal that I don’t think has been discussed very much: in contrast with regular journals, they are fundamentally non-exclusive, meaning that ANY overlay journal can in principle “publish” ANY paper. What this non-exclusivity means is that there is no jockeying between journals to publish the “obviously important” papers, which have a perhaps slightly elevated chance of actually being important. You know, like “we sequenced 10x more single cells than the last paper in a fancy journal” kind of papers. If you run an overlay journal, you never have to gaze longingly at those “high impact” papers—if you want to publish it, just add it to your overlay!

What are the consequences of non-exclusivity? Primarily, I think it would serve to diminish the value of “obviously important” papers. Everyone can identify them based on authors and number of genomes sequenced or whatever, so there’s really not that much value in including them per se. It would be like saying “Here’s my playlist, it’s like a copy of the Billboard Top 40”. Nobody’s going to look to your overlay journal for that kind of stuff (which you can readily get from CNS or Twitter). Rather, the real value would be in making lists of papers that are awesome but might otherwise be overlooked—essentially a hipster playlist. As an editor, your cache would be in your ability to identify these new, cool papers and making Michael Cera-esque mixtapes out of them. Can leave the Hot 100 to Casey Kasem/Spotify algorithms.

Measuring the importance of an overlay journal would also be interesting. Clearly, impact factor is not a useful metric, since anybody can make their impact factor as high as they want by including highly cited papers. I would guess a far more sensible metric would be number of followers of the journal (which makes more sense anyway).

Another interesting aspect of an overlay journal is that it can be retrospective. You could include old papers as well, highlighting old gems that may have been forgotten.

Of course, an interesting question is whether there is any difference between an overlay journal and someone’s Twitter feed. Not sure, actually…

Also, thoughts on existing journals that have hipster qualities to them? I vote Current Biology, my lab votes eLife.
