Extracting Data Sample Clauses

Extracting Data. The working groups responsible for collection development and technical services should agree what bibliographic, circulation, and item data is extracted from catalogs for analysis and what holding lookups they want made to compare overlap with, for example: OCLC, HathiTrust and the Internet Archive. Bibliographic data will be required to identify the title being analyzed, for use in holding comparisons with larger resources such as OCLC, and for subject information. Item level data will be required to show holdings at member libraries and their usage. Libraries should remember to check whether the systems stores usage in multiple locations for example, in-house use or reserves. The complexity of the data extract means that initiatives will likely only have one opportunity to get it right, so it’s important that the decision factors are represented in the extracted data. Although not all of the data extracted may eventually be used to base retention decisions on, it is better to have the data and be able to discount it than to not have it to refer to. MSCS found that both collection development and technical services staff were required in planning the data extract to ensure decision factors were represented in the data. Collection development staff were needed because they would eventually be responsible for analyzing the data and making retention decisions and technical services staff were needed because they know what data is available and how it’s used by the libraries. The MSCS Systems Librarian extracted the following data elements for analysis: Bib Level Identification ● Record number ● OCLC number Item Level Identification ● Item record number ● Created date ● Barcode ● Itype (value in the item that defines how it circulates) ● Volume and copy ● Item call number ● Location Usage ● Total checkout and total renewal ● Year to date circulation ● Last year circulation ● Last checkin ● Out date ● Last out date ● Reserve notes ● Internal use count ● Icode2 (contributed to union catalog) ● Circulation Status Ensuring only records that had valid OCLC numbers were exported required some significant data wrangling on the part of our Systems Librarian (e.g. not exporting brief order records, brief circulation records, etc.).
