Federated search engines and link resolvers : offering clients an alternative route to information resources
Report on an evaluation of federated search engines and link resolvers conducted at the University of Pretoria
Use the above to access the following:
- Evaluation Instrument
- Comparative Evaluation
During our thorough dynamic summative and formative (and independent) evaluation we only looked at commercial products - from the evaluation we managed to list them according to our preferences, but none were fully up to our standards at the time (November 2005). We in stead decided to go for the Google Scholar option. We use Google Scholar as our federated search engine (also to search across subscription e-resources), and ScholarSFX (available free of charge to eIFL countries) as a full text link resolver. The motivation behind this is because we were not sure whether a federated solution will solve our problems - there are also disadvantages to using federated search engines, e.g. e-resources with limiting access being occupied by unnecessary searches running through that e-resource/database. Another reason is - students who want to conduct searches within specific databases are happy to do so - some of the functionalities in individual databases are lost when searching the database via a federated search engine. We rather wanted to target students who avoid the library resources because it is so difficult to find their way through the maze of hundreds of databases, and who are not aware of the resources.
Since our clients use Google, and want and prefer a Google interface, we decided to find ways on how to utilise Google Scholar to the advantage of ourselves and our clients. Through Google Scholar we would like to make our clients more aware of the valuable resources to which we subscribe. We are of the opinion that Google Scholar and Scholar SFX offer many of the advantages a federated search product and link resolver would have offered. I would like to encourage you to have a look at a presentation recently by myself and Sunette Steynberg , available on our UPSpace (DSpace) institutional repository at:

Title: Power-searching the "3-click" world: a federated search solution for clients at the University of Pretoria
I doubt if we will go for a federated search engine and link resolver in the near future, and are happy with what we can achieve with Google Scholar and Scholar SFX for now (free of charge!) If you need some further input or comments from our side, or have any specific questions, please don't hesitate to contact us.
