The number of titles owned by the Commonwealth eBook Collections program varies by product and is hybrid for both licensing and lending models.

Axis360
In Axis 360, both perpetual licenses and short-term licenses (when those are the only available option) are purchased. The licenses are for the one-book-one-user lending model and have content portability clauses so there is no true "ownership" of titles. 

BiblioBoard​
In BiblioBoard, both perpetual and short-term licenses are purchased.  All content here, regardless of the license duration, is available via the unlimited simultaneous use lending model. The idea is to take a "try before you buy" approach with a plan to license more in the beginning and to slowly shift the scale to ownership in a way that maximizes the amount of content that can be made available to libraries.

Ebook Central
In Ebook Central, a carefully curated profile is based on cost, publication date and including/excluding certain publishers. Titles are not owned but instead "rented" as patrons use them via the short-term loan lending model. The program only pays for content that is used and from a patron perspective, titles are essentially available via unlimited simultaneous use.
