I’m curious about how this works? How is it that they make it financially difficult to leave?
I’m not sure exactly what corsair means, but it might be something like this. As I understand it, to get a Missal and a hymnal from OCP in the pews,
it costs $4.50/year. With WLP, it costs even less:
$4.20/year. If a parish has been paying exactly that price for a decade or two, and is used to just maintaining a bunch of subscriptions, I imagine it would be difficult to make a switch to any other system.
Say a traditionalist-leaning music director was looking to invest in the new
Vatican II Hymnal. It includes all the readings for all three years of the rotation, as well as the texts of the propers and a good bunch of hymns, so it could theoretically serve as the only book a parish needs in the pews. But even with its being sold at cost, it will cost $15 at least. Picture that music director explaining to his pastor (who is a good shepherd and well-meaning but sees nothing wrong with OCP) that this year the music program is going to spend $6000 instead of $1800 on books alone. I imagine the answer would be “Yeah… no.” And that’s with a book that will be sold as cheaply as possible and can perhaps cover everything you need. Even if you think the new hardcover book(s) will last 10 years and so eventually make up the cost, it’s hard to justify spending so much in one go when the big-publisher softcover subscription model is so easy and familiar. I suppose the parish could borrow the money, take out a long-term note from the bank or something, but that’s scary in itself.
The take into account the major publishers’ powerful marketing: they work hard to sell their books and their system to dioceses and individual parishes. All this is, as I understand it, the reason why the quasi-traditionalists at the CMAA and similar organizations and websites like to make themselves out as the creative-commons-license-loving, selling-books-at-cost, you-can-download-our-stuff-for-free saviors of the Catholic music world. And perhaps they really are.
