An item is accessioned when it is processed by ReCAP staff and shelved at the facility

Books must have a unique barcode and be in good condition

Accession data is tracked by both ReCAP and CUL

Each institution tracks different data associated with barcodes

Granular data is available only from CUL; ReCAP Coordinator uses it for analysis

FY04/05-FY09/FY10, Middle Phase. Continued effort to clear backlog, re-purpose library space and offset collection growth; 300k per year

FY10/11-, Restricted Phase. Slow-down a result of budget, delaying planned construction of new module; 150k per year

CLIO location is the encoding used by CUL to manage off-site collections

Distribution of CLIO locations looks different from the distribution of customer code

Often several CLIO locations correspond to the same customer code

Granular data from Voyager is available for ReCAP accessions

This allows analysis based on single or multiple facets

For example, the distribution of publication dates, format and languages


Monographs : all records with format “am” Only include complete dates 1850-2010 Substantial holdings of monographs

published between 1950 and 1990 Post-2003 materials were transferred

directly to ReCAP at the time of acquisition Approximately 30,000 new acquisitions per

year are sent directly to ReCAP Further analysis indicates that recent

publications are requested by patrons at a higher rate
