Analysis of EAST Retention Impact on Interlibrary Loan Transactions
Analyzing the impact of retention commitments on Interlibrary Loan (ILL) transactions, this study delves into the circulation patterns of retained items, digital surrogates utilization, and speed of delivery considerations. Key findings include a significant proportion of transactions with retention commitments, insights on items lent by EAST retaining libraries, and implications for future exploration on data digitization and local circulation. Join the quest for further exploration in this data-driven journey.

EAST ILL Stats Access Working Group Results PAN Short January 27, 2023
2021-2022 Access Working Group Stats Subgroup 1. Does retention change the ILL pattern? 1. Do retained items circulate more than non-retained titles? 1. How many requests could have been fulfilled by a digital surrogate? 1. Would seeing the percentage of retained items lent via ILL, both to East members, and outside of EAST be useful? 1. Is speed of delivery, or turnaround time, important? Not just can we access, but can we access quickly ?
Sources of Data - 2019 OCLC GAC data RapidR (returnables) OCLC API for determining retention status HathiTrust and Internet Archives APIs to determine digital surrogates
Data pulled into Tableau to query and visualize
Number of EAST Retentions on Loaned Material
Conclusions ~44% of all the ILL transactions analyzed had a retention commitment > 6% were lent by the EAST retaining library 50% had only ONE EAST retention commitment ~ 70% of the retained titles lent were returnables 25% had only 1 retention and lacked a digital surrogate. https://bit.ly/EASTILLStats
Future projects and exploration Explore 2022 Data Digitization of Held By One and No Digital Surrogate Explore Other Sources of Data: Local Systems data e.g. Alma stats Illiad IDS customers - can get retention information into data Local circulation (do retained titles circulate locally more?)
