When I lead services from the BCP, I generally only announce the page number when I have to skip or if we are turning to an entirely different section, such as to a Psalm. This is only for Morning or Evening Prayer however, as we publish a bulletin with the pages numbers for every prayer and reading printed in it, along with whatever citations are appropriate (hyman number and name, scriptural book, chapter and verse, etc.).

Announcing the page number for a Psalm (really unnecessary as you can simply turn to the Psalm number - the page is unimportant) or a special prayer, such as a birthday or other commemoration, is fine, but the annoying repetition of page numbers every Sunday really does take away from the beauty and continuity of the service. I learned every word of the Holy Communion, both the priest's and the congregation's, starting at the ripe old age of eight as an altar boy. It isn't that difficult.
Of course, this seemingly arrogant and bullheaded priest's problem would go away if he only used a REAL Book of Common Prayer instead of that 1979 Book of Gobbledegook. And why multiple hymnals? I have always found "The Hymnal 1940" to have a more than adequate selection of songs, many of which are hardly ever used.
More doesn't always mean better.
