What are the most prominent names of the later and earlier books that address Islamic sects and denominations?

Among contemporary books on Islamic schools of thought and sects are: Al-Firaq by Jaber Tou'ayma, Al-Firaq wa al-Adyan by Nasser Al-Aql and Nasser Al-Qafari, Al-Mawsu'ah al-Muyassarah fi al-Firaq wal-Madhahib al-Mu'asirah, and Muhadarat fi al-Nasraniyah by Muhammad Abu Zahrah.

Among older books are: Maqalat al-Islamiyyin by Abu al-Hasan al-Ash'ari, Al-Fasl fi al-Milal wal-Ahwa' wal-Nihal by Ibn Hazm, Al-Milal wal-Nihal by Al-Shahrastani, Al-Farq bayn al-Firaq by Al-Baghdadi, and Al-Muntaqa min Minhaj al-I'tidal by Al-Hafiz Al-Dhahabi.

It must be noted that the saved sect is Ahl al-Sunnah wal-Jama'ah. Those who are not deeply rooted in the correct creed should not delve into the doctrines of other sects to avoid doubts, except for specialists or callers (to Islam) after solidifying their correct creed.
