Thanks, Suzanne!

It looks like Simultaneous Use ("always available") titles show 999,999 copies owned, and Cost Per Circ ("limited availability") titles show 500,000 copies owned. Do we want to distinguish between those?

If it's too much of a momentum killer, we can open a separate bug for this, but we'll want to I18N'ize those strings sooner or later.

NOBLE doesn't have any Cost Per Circ items yet, so we don't have the details on exactly how they work. But I would think from the patron's perspective they would also be always available, unless there's a configuration that restricts the number of times they can be checked out that way.

Jason, I figured the strings would be a I18N might be a problem.

The patch just committed for bug 1710512 has a model for how the I18N can be handled.

This branch adds internationalization to the "Always available" label

Here is a branch that adds a distinction between simultaneous use and cost per circ titles as noted by Jeff in comment #2. Simultaneous use titles will display "Always available" while cost per circ titles will display "Limited availability." I'm not sure that language is meaningful to patrons but that is the language Overdrive uses. Input from someone with cost per circ titles appreciated.

The API is not returning Cost per Circ items with limitedAvailability as the lending model and 500,000 as copies owned as specified in the v1 documentation for the availability API:

https://developer.overdrive.com/apis/library-availability

The version 2 API documentation does not mention Cost per Circ specifically:

https://developer.overdrive.com/apis/library-availability-new

I tested both the v1 and v2 availability API's using overdrive-api-checker.pl and found that Cost per Circ titles are returned with a lending model of normal and 1 copy owned/1 copy available:

"available":true,
    "availabilityType":"Normal",
    "copiesOwned":1,
    "copiesAvailable":1,
    "numberOfHolds":0

We don't have many Cost per Circ items so would appreciate someone else confirming this.

The Overdrive API Reference Guide says this about the Cost per Circ lending model:

"Cost Per Circ titles look identical to One Copy/One User titles in OverDrive's APIs. The only difference is that they will always show one owned copy, and they will never become unavailable unless the library's monthly budget runs out."
