I've Googled this and got a book from 1977. I understand that the Dirshu Mishna Berura has many 57th century dinim, but I don't believe that it is being updated to the 58th. With technology and medicine changing the landscape dramatically, where are the dinim of say Rav Auerbach and the Tzitz Eliezer being published (aside obviously from their own sefarim)? Or was the Aruch HaShulchan, the Kaf HaChaim, and the Mishna Berura the tachlit of halachic sefarim til Mashiach comes? Are there contemporary encyclopedias?
