Note
It is unlikely that more than a few public libraries possess files so complete as to give access to all of these essays, and even if the magazines were readily obtainable at libraries they would almost certainly have to be read in those institutions. The nature of the material, its timeliness (Mr. Veblen deals with ideas in such a manner as to give the date of composition a secondary importance), and the fact that it would otherwise be lost to all save diligent excavators, explain its preservation in this form.
