Three information systems serving the Library and Information Science professionals are presented: 1) the E-LIS (E-prints in Library and Information Science) open access repository, 2) the online directory EXIT (Experts in Information Handling), and 3) IraLIS (International Registry of Authors - Links to Identify Scientists), a platform intended to normalize author names according to the universally accepted format of only 2-character strings with an optional middle initial -, and a database of name variants used by each author. Thanks to the collaboration between the responsible people of these projects there have been established automatic links that add value to the individual utility of each system. The core of the system is the EXIT directory, from which automated queries to E-LIS and IraLIS, and other resources as ResearcherID, Google Scholar, Google, Yahoo, Bing, Touchgraphic, etc., are launched.
