Estonian Libraries Network Consortium (ELNET Consortium) is a non-profit organization representing the common public interests of libraries. ELNET Consortium libraries have 4 cooperation projects: e-catalogue ESTER, Estonian article database ISE, the Estonian Subject Thesaurus (EMS) and common procurements of e-resources. The online catalogue ESTER is the shared catalogue of the ELNET Consortium member libraries (containing information on all documents acquired by these libraries). The catalogue also contains data on the holdings of university college libraries and special libraries. Today the shared catalogue is supplemented by 13 libraries, all of them using the integrated library system Millennium that is managed by the consortium (the software is developed by UScompany Innovative Interfaces). On January 2009 the database of Estonian articles, Index Scriptorium Estoniae (ISE), at http://ise.elnet.ee/ was opened to users. This database, the result of cooperation between 12 libraries in the ELNET Consortium, contains articles, from newspapers, magazines and journals, serial publications and anthologies and collections from the 1900s on allowing the full-text to be accessed in free digital archives and Web publications. The Estonian Subject Thesaurus is a universal controlled vocabulary in Estonian for indexing and searching various library materials. The subject terms fromEMS are used
