We Have to Thank Them All

Jonathan Eisen at The Tree of Life is venting about journals that restrict the number of references authors are allowed to cite (usually for space reasons). "A HUGE part of science is giving and getting credit for work. And thus it baffles me why some journals enforce strict restrictions on the number of references allowed," Eisen writes. It also makes it more and more challenging to give proper credit to the previous works that informed your own, he notes. "One option to solve this would be for these journals to allow expanded reference lists in online material - and for these lists to somehow get picked up by citation indexing systems."
