Perhaps I've simply never found the feature but for multi-volume books such as Hefele, Charles Joseph. A History of the Councils of the Church. Translated by Henry Nutcombe Oxenham. Vol. 1-5. Edinburgh: T&T Clark, 1876. it is difficult to guess which volume one needs. Please make it simple to navigate to prior/next volumes.
Orthodox Bishop Alfeyev: "To be a theologian means to have experience of a personal encounter with God through prayer and worship."; Orthodox proverb: "We know where the Church is, we do not know where it is not."
