There are not many compilations of Nabokov's works in English. But there are many (maybe a couple hundred) in Russian, most unauthorized. Though I didn't create a separate section for them in the 1986 bibliography, they were included in the A items. Now, however, separate sections for them are part of my revised and updated edition plan. They will be added to the draft pages you can see on my blog, Nabokov in Print, at vnbiblio.com, after I complete the A items (I'm just finishing them up now with the final entry for all the Lolitas) and the D items (translations). The compilations will be known as L items. Compilations in translation by others will be known as M items.

A few more examples of L items in English that Rowberry missed:

The three volumes from the Library of America

A Guide to Berlin and Other Stories (published in Japan)

Time and Ebb (published in France)

I wouldn't include the various Playboy short story collections since they are anthology's of many authors with only one work by Nabokov each time. If someone wanted to track down the inclusions of individual Nabokov's works in all such anthologies, he could construct a pile higher than the Admiralty Spire.

And while talking about publisher-driven books, one could make a case for the extractions from Penguin: We Came to Know... (Lolita); Now Remember (Speak, Memory); Terra Incognita (The Collected Stories); Cloud, Castle, Lake (The Collected Stories); and other variations.
