Library Supply Distribution Co. (Konyvtarellato Kozhasznu Tarsasag - KELLO) carried out the modernisation of its services in the second half of 2004. The two main pillars of the modernisation were the conversion of the KELLO bibliographical database into the HunTeka integrated system, as well as the introduction of SAP. As a result of the integration of HunTeka and SAP, KELLO launched a new homepage and a range of enhanced services for its library customers as of Dec 1, 2004. The present article is an edited version of the presentation given at the Networkshop 2005 conference. It summarises the lessons learned from the switch to the new system, presents the new services and outlines the main areas of cooperation with SAP.
