The Library of America is a nonprofit publisher founded in 1979 with the aim "to help preserve the nation's cultural heritage by publishing America's best and most significant writing in durable and authoritative editions" (see http://www.loa.org/page.jsp?id=201 ). Growing steadily since its foundation, its 2010 edition now includes over 200 volumes, bringing together American authors of note from colonial writers to our contemporaries -- a truly magnificent undertaking!

Yet, for copyright reasons, due to as-yet to be concluded (or initiated?!) negotiations with the respective authors' estates, or for whatever other reasons -- not the least of which is, of course, the sheer abundance of writerly output available for selection -- some of America's foremost writers are still missing from the collection (and the more it grows, the more their absence is noticeable). So: who/which in your opinion are the as-yet missing authors and works that would equally deserve to be included in the Library of America's eminent collection?

(Please note: The complete catalogue of the Library of America can be found here: http://www.loa.org/catalog.jsp?sort=1 . Before adding a given book to this list, please double check whether the author or individual work you are planning to add is really not yet represented in the catalogue.)
