Two and a half years have passed since libraries first started to make available the contents of their catalogues to the major Internet search engines, Google, Yahoo and Microsoft Network (MSN). The paper examines the success of this initiative and various aspects including search engine selection policies, ranking, service evolution and statistics in terms of "click throughs" and "conversions". The benefits to libraries of exposing their collections as broadly as possible, additional sites to GYM and methods of exposure are examined. But there is becoming a serious "discovery to delivery gap"; linking seamlessly to delivery systems is a necessity if libraries are to sit proudly alongside web sites like online book stores and match them for ease of requesting materials. Recent developments in standards and in OCLC's worldcat.org are presented as steps towards improvement in the delivery area.
