Finding—more like, eking out!—time from within a back-breaking work schedule, I recently managed to review back-to-back four manuscripts for publication in diverse journals. The topics in these papers touched my work only marginally, in that they belonged to the broad areas of microbiology, antibodies and immunodiagnostics. A chance remark by a professional friend—”Your reviews are impressively long and detailed…“—got me thinking about my overall experience reviewing scientific manuscripts. “Long and detailed” is probably why it takes me a considerable time and effort to go through the paper, occasionally check the references, and note down my thoughts in the margin, either on paper (i.e. on a print-out), or electronically (annotating the manuscript PDF, my preferred mode). Not unknown to anyone who is familiar with the process of scientific publishing and the world of biomedical journals, Peer Review is a mechanism that attracts a significant amount of controversy. So why do I keep investing the time and effort towards it? More after the fold.
