I was influenced to make a list of sforim, that have segulas associated with them, by the following post from a most respectable blog - A Simple Jew:
A Simple Jew: A House Without A Copy - More On Segulos
Likutei Mohoran (and all the sforim of Reb Nachman of Breslov) – Reb Nachman himself says in Chayei Mohoran (Tzadik) that everyone should acquire his sforim to keep in their house even if it just sits on the shelf unused, because they are a great protection for ones possessions and protects from all sorts of damages.
Kav Hayosher – The author says everyone should buy it and review it and they will have success in everything. The Pri Migadim says that learning the sefer is healing for the soul and the body.
Yesod V’shoresh Ha’avodah- the author (Reb Alexander Ziskind of Horodna) in his tzavah says he will be a “Good Advocate” for whoever learns it, even if they don’t accept anything from the sefer. (I’ll let you in on a secret. I don’t think it is possible to learn this sefer or any of the Sforim Hakedoshim and not be affected.) Reb Moshe Mordechai of Lelov says learning it is a segula for yiras shomayim.
Maharal Tzintz- said he would be an intermediary in Olam Haba for whoever helps to publish his sforim. See website http://www.tzintz.org/
(From here on was taken from Sefer Segulas HaBesht V’Talmidov)
For an easy labor, the Sefer Shulchan Melochom says the following sforim are a segula to put under the woman’s head: Noam Elimelech, Ohr Hachochmoh or Kedushas Levi. (The sforim should have 2 coverings because the delivery room could be a halachically dirty place-get the small versions of these sforim and wrap it in 2 small bags)
Nevi’im (Prophets) - Reb Pinchos of Korets told his son that learning Nevi’im strengthens emunah.
Ohr Hagonuz (Reb Yehuda Leib HaKohen of Anipoli)- In the haskama to the sefer, Reb Mordechai of Chernobyl writes that everyone should acquire this holy sefer, as a zchus and shmira for himself and descendants for generations.
Ohr Hachaim – Reb Pinchos of Koritz says it’s a shmira for the house.
Heichal Habracha (Komarna) – Anyone who has it in their house will be saved from all bad things, sicknesses and from lacking their needs and the house will be filled with blessings of Hashem and all good, success, wealth and life, for him and children without pause. (Masei Hasheim)
Rambam – Magid of Mezrich wrote in a letter to the Baal Hatanya that he should learn Rambam after Maariv, because it is a segula for yiras shomayim and to get rid of chitzonim. The Apta Rov says the golden language of the Rambam is a segula for the Nefesh, Ruach and Neshoma.
Kedushas Levi – It’s known and accepted from tzadikim that it is a segula for the sweetening of harsh judgements to have it in every Jewish house.
Toldos Yaakov Yosef – Segula to put under the head of a sick person.
Raziel Hamalach – Also, a segula to put under the head of a sick person
Otzar Hachaim - (sefer on Taryag mitzvahs), the author says whoever learns this sefer in depth is assured that he will go to Olam Haba without having to be a gilgul and he says “I guarantee it”.
Siddur Ohr Hayosher – Segula for Yiras Hashem
Ber Mayim Chaim - learning it does a great favor for the soul
Tur & Bais Yosef – Sar Sholom of Belz says learning it is a segula for yiras shomayim and long life. Magid of Mezrich wrote a letter to the Baal Hatanya, saying in the name of the Baal Shem Tov, to learn Tur with Bais Yosef, wearing tefilin of Rabbeinu Tam, because it purifies and helps the neshoma.
Chok L’Yisroel - Magid of Mezrich wrote a letter to the Baal Hatanya saying he should learn Chok L’Yisroel wearing tefilin of Rabbeinu Tam everyday.
Sharei Kedusha (Reb Chaim Vital) – Reb Pinchos of Koritz says raises up a person “m’bechinas eitz hadaas tov v’ra” (can’t say I know what that means – just quoting)

Tshuvas Chasam Sofer – Reb Yisachor Dov of Belz says every row of this sefer is a segula for tshuva
Yesod Ha’avodah – the author says his sforim are a segula for Ahavas Hashem
Meor V’shemesh – learning it is a segula for yiras shomayim
Meor Einayim – Reb Yochonon of Rachmastrivka says that if someone is in an eis tzarah it is a segula to learn the sefer. Reb Yitzchok of Skver says just like in times past learning Zohar was beneficial to the neshama, so too in these generations learning Meor Einayim is a segula for the neshama. Shiniva Rov says every Jew should have a copy in their talis/tefilin bag and learn from it every day while wearing tefilin – and this is a “big segula”.
Maharik – Reb Yisachor Dov of Belz told someone that had internal bleeding, to learn from this sefer and he was healed

Menoras Hamaor – Reb Mendel of Rimanov says it is a segula for a sick person to learn
Mesilas Yesharim – the Magid of Kozhnitz says he attained all his levels from this sefer
Noam Elimelech – Reb Chonoh of Kalashitz advised a student, who was straying from the proper path, to say a page every day, whether he understands it or not, because even just turning the pages is a segula for yiras shomayim. The student became a G-d fearing Jew, and so too, his children.
Siduro Shel Shabbos – learning it helps one have a real taste of the holy Shabbos
Avnei Nezer – The author said before his passing that if one learns from his sforim, he will be a protector and helper after his death exactly like when he was alive.
Chida – Reb Elimelech of Lizhensk says that the sforim of the Chida nullified all sifrei minus, and learning the Chida’s sforim will let someone have unshakeable emunah.

Shulchon Aruch – Sefer Hamidos (Reb Nachman of Breslov) says learning it brings to yirah.
Simlah Chadasha – it is a segula for a shochet to learn- to protect him from having any flaws in his slaughtering.
Tomer Devorah – Satmar Rov had a kabala from the Divrei Chaim of Sanz that the sefer is a segula for the “known disease” – may Hashem save us, and if one isn’t able to learn it himself he should have someone read it in front of him.
