As technology marches on, there may be one job that will become extinct: Page Turners. The ipad is sinking its claws into many a player, as I type. However, in the meantime, there will still be the need for those steely-eyed warriors who safeguard the page turn. Some links that I recently found:
An NPR interview of David Evan Thomas, who has page-turned for X, Y and Z.
Wall Street Journal's interview with Randy Knee, who turns pages at Carnegie Hall.
"All you never wanted to know about page turning!", an article written by Michael Hammer, also called A Page Turner's Survival Guide, offers several ideas on the subject.
WNYC has a couple of bits on the subject: Turn the page - if you dare written by John Schaefer, and It's More Than Just Turning Pages, an interview of Carnegie Hall turners.
