After 14 years on Saturdays, the Times Review of Books moved to Sundays this week in 1911. This notice appeared that Saturday, with similar notices appearing throughout the week. It could bee seen as more information than the reader needs about why the section is moving, but I find it refreshingly open and honest in its discussion of circulation and advertising issues. I imagine that a similar notice today would simply be reduced to “Now On Sundays!”
In transferring to the Sunday issue The Review of Books, which has for fourteen years formed a part of the Saturday morning issue of The Times, a change is made of which the necessity, long ago foreseen, has become so urgent that it can no longer be deferred. The Review of Books will to-morrow, and henceforth, be issued with The Sunday Times.
The reasons which make this change imperative concern both The Times and its readers. Owing to the increased number of pages required for the volume of news and advertisements printed in the daily edition on Saturday, it has of late frequently become necessary to reduce the size of The Review of Books. We are unwilling to adopt permanently that way out of the difficulty. There is but one other way. It is by making The Review of Books a part of the Sunday edition. This change, by avoiding the necessity of haste, makes it possible to improve the printing and the appearance of The Review; it will thus be more acceptable to its readers and better suited to binding or laying away for reference.
While this change has been long in contemplation, it has been deferred, out of regard to the interests both of readers and of advertisers, until the circulation of The Sunday Times should approximate that of the daily issue, thus continuing to give The Review of Books a circulation much larger than that of any other publication in the world devoted to the news of books and the discussion of their contents. Of this great circulation, pre-eminently a home circulation, The Review of Books, forming a part of the Sunday issue, will have the full benefit.
Moreover, it is believed that, issued on Sunday, The Review of Books will have an enhanced value for pleasure and instruction. It will be read with more thoughtful attention on a day when release from the cares and demands of week-day vocations leaves the reader free to enjoy its pages. As a part of the Sunday edition it will give new interest and value to that issue of The Times, and will itself, we are confident, be read with profit and satisfaction.
Today the New York Times Book Review remains published on Sundays, but has the further distinction of being the only section* in the Times that you can subscribe to separately from the rest of the paper.
*as far as I know.
