The CPU method is a quantitative method to use when evaluating collections, but should be used in conjunction with qualitative assessments of a resource in order to show a more rounded evaluation of the resource. The purpose of a CPU analysis can be varied. The following are some examples. The majority of publishers and platform providers for online resources make available usage statistics for the resources they provide on an annual basis, usually by the calendar year.

Some publishers may provide only a few of the recent months. Those publishers and platform providers that allow customers administrative access to the publishing platform often have the option to gather usage statistics by other customized time frames. One may gather the usage statistics annually or as needed, but unless usage statistics are needed more often, gathering them once a year starting in mid-to-late February will usually be enough time for the publishers and platform providers to have loaded the statistics for the previous full calendar year.

Gathering usage statistics for multiple publishers and platforms allows use of the CPU to compare value across publishers. Automated gathering of usage statistics through the SUSHI protocol is also available for use with many publishers. LibInsight is another potential data storage platform. Alternatively, spreadsheets may be stored on a local server. Historical data reveals trends of use throughout a month period and over several periods.

Store the spreadsheets of usage statistics to build an archive of additional assessment criteria that will help track the value of paying for the resource. One of the first analysis steps involves generating relevant e-journal title lists to serve as the foundation to build the cost per use analytical report. As a general rule, there are fewer silos within some next-generation library services platforms. The free, open source tool OpenRefine may help in managing the data needed for the analysis.

Whatever the data source, the title list can be created by exporting a data file and importing it into a spreadsheet. The exported file with local acquisitions data then can be merged with the usage data. If list price is available at the title level, then another cost-per-use formula can be applied to the list price, as well.

The titles in the CPU report can also be mapped to subject areas using LC classification or academic department names. The cost per use analysis can be structured to include CPU thresholds by expenditures and cost per use.

For example, Michael Arthur offers a case study from the University of Alabama see table 1 , in which resources are tallied by both price range and cost per use. CPU thresholds should be discussed and determined by project members.

In other words, the larger the continuing resources budget, the greater the acceptable CPU threshold for retaining titles; and the converse may be applicable for institutions with smaller continuing resources budgets. Uses per title: 11— titles Quad D:. Uses per title: 2—10 titles Sample of high use for a bundle of 4, titles: Quad C:. Uses per title: 11— 3, titles Quad D:. Uses per title: 2—10 titles Thresholds: Establishing criteria which a resource can be evaluated against relative to high use and low cost is another way to put a rough sort on usage.

By use: Decide on a usage number below which low usage is not considered impactful. For example, if uses is chosen as a good mark of usage, does the title in question fall below the threshold? By cost per use: Decide on a cost per use above which higher cost per use is considered unacceptable. This threshold might be based on the cost of alternative access to a non-subscribed resource. Easy to follow.

No jargon. Pictures helped. Didn't match my screen. Incorrect instructions. Too technical. Not enough information. Not enough pictures. The market expressed a preference for a simple pricing structure, where each service can be easily identified.

Stability of the pricing policy and fee structure, i. One collateralisation item plus both instructions of each auto-collateralisation leg are charged per ISIN and providing account, i.

These items have been priced as free of charge, presuming that actual use of T2S will remain within this expected consumption pattern over time. However, should there be greater than expected use of T2S resources and if the volume distribution pattern is different from expected, thus adversely affecting T2S performance, a charge for these items will be reconsidered.

The Eurosystem regularly reviews the actual volumes against expected patterns for the different items. However, should DCAs consume more T2S resources than expected, thus adversely affecting T2S performance, charging for these items will be reconsidered. The Eurosystem regularly reviews the matter together with the central banks operating the DCAs.
