The paper outlines the opportunities that Learning object has put forward for teaching and learning. Focusing on a particular aspect of learning object retrieval system i.e., design and develop the mechanism of  learning object on library and information science learning object (LISLO) using open source software (Greenstone) and open standards (IEEE LOM), the paper discusses about the online and offline CD ROM product and services of LISLO. It enhance modified IEEE LOM metadata incorporation for digital archiving and retrieval system  using Greenstone Metadata schema (GEMS).
