This is something Silliman has calculated before and I’ll copy it here in hopes I won’t mislay it readily
[A]t two books per week, you could read the poetry books published in the U.S. just in 2006 by roughly 2045. If you read a book a day, however, you can get it done by the end of 2014 or thereabouts. And then you could begin on 2007.
This is obviously where canons, anthologies and selection comes in. You really donâ€™t want to read all 4,000 titles that will be published this year, regardless of what your allegiance is to aesthetic camps. Indeed, you canâ€™t possibly read just the post-avant texts that will be published this year, just because itâ€™s probably the largest single semi-coherent grouping of those titles today. It would not shock me to discover that, of the 4,000 titles, as many as 1,500 can be identified as post-avant [snip].
And the last 1,500 have no allegiance or connection really to anything. Some of these are fiercely independent isolatos, but the bulk are no more well read than are my students this week. These authors are disconnected because they really are disconnected.
