Providing access to the full text of cataloged articles is a highly de- sirable feature for a digital library. However, in many such systems, not all metadata records have (a direct pointer to) a corresponding full-text document. In this paper, we present a new service for finding missing documents from dig- ital library catalogs. This service is implemented as a software component in order to be readily deployable to existing systems. It works as a parameterized meta-search engine and allows digital library administrators to easily set up a search strategy, i.e., a list of existing search engines to be queried for the miss- ing document, as well as the filtering and ranking policies to be applied to the results retrieved by each engine. We present a performance evaluation of our service with respect to its efficiency and the effectiveness of a suggested search strategy for collections in the computer science and in the biomedical and life sciences fields.
