This collection documents my evaluation of various Web search engines and subject catalogs. It is intended as a guide for new users and as a checklist for Internet users seeking particular functionality in their tools. The Matrix currently describes more than 12 servers, and many more are planned. This is not a finished product, but a dynamic document that stays current and relevant. I plan on adding new services and revising outdated information.

I am currently finishing the necessary work to setup the Matrix. My current effort is to build the graphic checklist and link the image to specific portions of the collection, then complete the evaluation portions of the pages. The next step will then be to complete the administrative documents, and post public announcements to various newsgroups and What's New services. Finally, I plan on keeping the matrix alive and current... a continuing process of research and updates.


Administrative Documents

Graphical Evaluation Matrix (Text Only) [NEW]
The goal of the project, this is a graphic checklist identifying key features and support issues I found relevant. Each section of the charts are linked to the relevant documents in the collection.
Sample Evaluation
This is the template document from which I build each evaluation. It demonstrates the criteria and organization of individual evaluations.

Vocabulary Page
A reference page for selected terms used throughout this collection. The discussion assumes you have familiarity with basic Web concepts and terms; if not, you should refer to the Overview of the Internet documents.

Planned Servers
A list of Web servers that I plan on evaluating. Some are more important than others, but if you know or use a service that isn't on the list mail me the URL and I will add it.

Matrix Highlights [HOT]
As I built the Matrix, I have found several pages that really stand out from the rest. These are not the search engines themselves, but additional or related services that offer value-added services.
