Logos puts titles into “Pre-Pub” to help gauge user interest in various resources. When users pre-order a resource, that helps to cover the cost of production. If/when enough users pre-order, the title goes into development and the user gets it at the discounted pre-pub price when it “ships” (i.e., when it is completed).
Here is a short description from Logos’s Pre-Pub About page:
Prices start low and increase over time so the sooner you pre-order, the less you pay. We don’t charge you until your pre-order is ready, and we’ll send you a reminder email a few weeks before. If you decide you don’t want the resource anymore, you can cancel your pre-order at any time.
Here is a compilation of the newest Pre-Pub titles. (This one from Oxford University Press is pricey but looks good; here is When God Spoke Greek, which had enough pre-pub orders that it’s already under development and will probably ship within a month.)
Here is the Pre-Pub list sorted by Progress or “ship date,” so you can see which ones are almost ready to go–with the pre-order discount still applying, at least for now. There’s a bunch of Eerdmans stuff that will go out on August 6, including this collection that looks especially useful to pastors, including the book that is pictured above.
Here’s a short overview video of how Pre-Pub in Logos works:
