I've been seeing this year how big a dent I can make in Jules Verne's Voyages Extraodinaires, and since the year is halfway through it seems appropriate to see how progress is coming with it. I've been doing two different things, Notes and Fortnightly Books, and the latter includes the Verne works I did before this year. Bold with link indicates all the ones I have done one of the two for; N indicates a Note, F indicates a Fortnightly Book.

So we are at 19/54, which is just over one-third. I literally have Begum's Millions, Robur the Conqueror, Master of the World, The Mighty Orinoco, and The Invasion of the Sea stacked in a pile and waiting in line for the Fortnightly Book, and somewhere I have Twenty Thousand Leagues, so all of those are guaranteed. Not all the works are easily found, and there are more books than weeks in the year, so I never expected to get all the way through. But it looks like I've a good chance of hitting two-thirds to three-quarters.
