Storage, preservation and access of Master's and PhD theses as well as their abstracts in an electronic form provide unique opportunities to the academic community in Lithuania as well as worldwide. The main aims of this project were to establish an archive (Lithuanian ETD IS) of Lithuanian student final year projects, PhD theses and their abstracts in an electronic form (ETD). This archive should become a part of the Lithuanian academic library network (LABT), ensuring registration and storage of ETD documents, and should be accessible by the academic community in Lithuania and the rest of the world. In order to develop the Lithuanian ETD IS, the most widely used formats and methods for access, retrieval and exchange with NDLTD and other national ETD projects were employed. A solution, ensuring efficient ETD registration, preservation, retrieval and access by users, is presented and discussed. Application of the ExLibris programming products (ALEPH500™, MetaLib™, SFX™), developed during the LABT project, was used.
