Open access (OA) publishing seeks to eliminate paywalls for users. It has largely succeeded, but new diversions and distractions built into the commercial Internet may create new barriers that will be harder to deal with.
Smaller independent and society publishers are finding it increasingly difficult to compete with the economies of scale around production, technology, and (most important) institutional sales that can be brought to bear by a large publisher. If you are a society that has been self-publishing for many decades, such effects may appear as only a recent headwind in a long publishing tradition. This headwind, however, is most likely not a temporary zephyr but rather a permanent fixture of the STM and scholarly publishing landscape, and one that will only increase in intensity. To understand why, it is helpful to look at the two vectors on which scale operates in STM and scholarly publishing: horizontal and vertical. While horizontal scale has long been the province of commercial publishers, society publishers are typically organized to take advantage of vertical scale. The headwinds are presently blowing along the horizontal plane, from the perspective of the society publisher.
