Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The Pennsylvania Academic Library Consortium, Inc. (PALCI) developed demand-driven acquisition (DDA) programs to facilitate resource sharing of e-monographs and to build collective ebook collections thereby complementing E-ZBorrow, the consortium’s print-based ILL service. Committed to perpetual ownership, PALCI’s programs deliberately eschewed aggregator models with STL (short term lease/ loan) thresholds in favor of purchasing upon the first substantial use at a negotiated multiplier. This unique approach to consortial DDA resulted in hundreds of titles triggered for purchase, many of which experienced post-purchase usage across the membership. It also resulted in irregular starts and stops and workflow frustrations illustrating challenges related to funding and communication. This article is intended to add an important case study to the literature on consortial DDA through a critical evaluation of PALCI’s programs with ebrary, EBSCO, and JSTOR. Perhaps more importantly, it is intended to inform consortial stakeholders about decisions to replicate (or not) PALCI’s programs in an effort to repeat successes and avoid past failures.
