Dear Chaveirim,
I want to call to your attention a new two-volume set of Seforim by Rav Kalman Krohn of Lakewood, which is literally an "encyclopedia" on this topic (to quote Rav Dovid Cohen's haskama). The two volumes contain 78 chapters and over 2,500 pages, and the bibliography contains approximately 600 sources!
The name of the set is "Vehiskadishtem" and the subtitle is "Midas HaYesod." It's part of a larger series entitled "Yisroel v'Oraysah" (I don't believe the other volumes in the series have been published yet).
Of note are a number of chapters in the second volume on many not-so-well-known Tikunim, such as having Kavana when saying a Bracha Rishonah and Bracha Achronah, reciting Birchas HaMazon from a siddur/bentcher, and washing Mayim Achronim right before bentching and not being mafsik.
The set has Haskamos from, among others, Rav Chaim Kanievsky, Rav Vosner, Rav Sternbuch and, as noted above, Rav Dovid Cohen. Rav Cohen writes something incredible (my translation): "I have no doubt that through [the author's] tremendous effort to write and publish this set, he has, by doing so, rectified the sin of this generation regarding Shemiras HaBris (Tikein ba'zeh chet'o shel Hador b'shemiras HaBris)."
