New this year

In addition to the three different covers, this year's biggest changes are the new base maps that have fixed a number of geographical issues from the past as well as an interactive map index in the PDF version. Four new map index pages are included before the main map section. I know many readers have been asking for this for over 20 years, and, better late than never, it's here now. In addition, page coverage has changed significantly in spots, especially near Coney Island, where several significant map errors from before have finally been resolved. Here's a sample of the the map index:

And for the first time, official station numbers have been included, as well as a six page Index of Stations. These identify a station on any given chaining line (how many 34th St. stations are there? How many 8th Avenues are there?). In the example below, the West Side IRT's Chambers St. station is #324, but the nearby IND Chambers St. station is #170.

Furthermore, every station has been linked to its Wikipedia entry. Of course, all the latest changes have been incorporated, including more signals, more historical notes, station numbers, and a handful of corrections were added this year. Over 800 hyperlinks were added for readers of the PDF version, and navigation within the PDF version was improved substantially.
