Level of duplication sought in candidate titles for WEST
The current level of print duplication among WEST libraries is one characteristic that makes a journal a
candidate for the Trust. Titles with moderate to high print duplication among member libraries are
candidates for the Western Regional Storage Trust. Titles with low duplication are not initially
candidates for the Trust. It is assumed that unique titles will be managed locally without the need for
cooperative action.
After (and in addition to) the current level of print duplication, other criteria are also considered (e.g.
electronic availability, scholarly/academic titles.)
The Trust is envisioned as a catalyst for space reclamation. By choosing titles that are widely held in
print and agreeing to retain one copy, the members can generate the greatest opportunity for space
reclamation across the network.
Collection Analysis
To determine levels of duplication, WEST members participated in an ambitious collection
analysis effort. In 2010, WEST library and storage facilities supplied more than one million
records of their journal holdings for a collection analysis effort. Records were ingested into a
database along with enriched metadata supplied by Ulrichs. Approximately one fifth of the
records (218,000) were suitable for analysis.
Based on an initial analysis of those records at the title level, WEST library and storage facilities
hold approximately 60,580 journal families (current and previous titles). Further overlap analysis
suggests that a high level of duplication among WEST libraries and storage facilities may be 5
copies and a moderate level may be 3-‐4 copies.
Table 1: Levels of Duplication within WEST Defined
These figures may be significantly understated (at the title level) due to limitations in the data
supplied for analysis. These figures may or may not be overstated at the holdings (volume)
level. Future analysis and capabilities may be needed to improve automated holdings level
analysis. The initial planning phase for WEST included analysis at the title level for all categories
except category 3, and preparation of title lists with proposed archive providers/locations.
Subsequent holdings analysis will occur in an implementation phase.
