Bradley, BenjaminPoster presented at the MLA & DLA Joint Library Conference, Cambridge, MD, May 2-4, 2018.As electronic resource collections continue to grow, librarians often struggle with maintaining these growing collections. Librarians need web-scale tools to manage e-resources in a web-scale discovery environment. This poster presents two tools I use to help manage e-resources. The first is a Ruby script originally developed by Kristina Spurgin, the E-Resource Access Checker. In the poster, I discuss how I use this tool and have developed the code further to meet my needs. The second tool is a Python script I have been developing which uses the OCLC WorldCat Search API to harvest metadata to supplement publisher provided metadata in our e-resource management tool, OCLC Collection Manager.en-USe-resourcesAutomationLibrariesMetadata TransformationMetadataOCLC WorldCat Search APIPresentation
