Tikkun Leil Shevi'i Shel Pesah - All About Mashiah

As can be found in Keri'ei Mo'ed and copied into text form by Hashem1.net 10 years ago, the Tikkun Leil Shevi'i Shel Pesah contains a great compilation of Mashiah-related sources that are to be read before halachic midnight on the 7th night of Pesah.  It was compiled by the Kabbalist Dayan R' Binyamin Halevi (5330-5436) from Tzefat in his book Hemdat Yamim.

However, as Hashem1.net points out, reading it is really beneficial any day of the year.
