I have joked about 2012 being "The Year of the Doorstop" because of the size of the books I've read and plan to read before the end of the year. 2013 will probably prove to be a sequel: "Year of the Doorstop, Part 2," if my plans hold. One of my intended reads is the entire Gulag Archipelago by Aleksandr Solzhenitsyn. I first read the series when I was a teenager, which means that comprehension and retention were almost nonexistent. I also have the benefit now of Anne Applebaum's remarkable book Gulag: A History.
For those not wanting to tackle three lengthy volumes of Solzhenitsyn's work may be interested in an excerpt from the introduction by Natalia Solzhenitsyn to the abridged version published in Russia in 2010. There's also a supposed introduction to Natalia Solzhenitsyn (although there's little about her). I'm hoping this means the abridged version will be available in English before too long
Speaking of doorstops, in the same issue at the same site is a look at three recent releases of the Iliad: two recent translations by Anthony Verity and Stephen Mitchell plus "Richmond Lattimore’s 1951 translation of the Iliad, which has just been re-issued (without alteration, but supplemented with maps, notes, and a useful introduction by Richard Martin." Looks like I may have at least one more addition to next year's plans from this trio.
Update (5 Oct 2012): Even more on the Iliad, including a look the new translations as well as many older ones.
