Over 1100 resources are described by subject or type of material - journals or software for example and evaluated. Searching facilities are good.
- P.A.M Resources in mathematicsProduced by the Physics-Astronomy-Mathematics Division of the US Special Libraries Association this gateway includes lists of useful links under the following categories: People (Directories/Biographies); Professional societies; Institutions; Reference sources; Preprints; and Pathfinders (Internet resources in mathematics).

- Math, Statistics, and Computational ScienceApplied mathematics, from NIST. Includes software.
- Na-NetThe NA-Net is a system developed to serve the community of numerical analysts and other researchers. The Na-Net provides two databases and a weekly digest to its members. It is basically a directory of those with an interest in numerical analysis and provides a means of easy communication and discussion.

- European Mathematical Information Service (EMIS)EMIS is supported by the European Mathematical Society (EMS), which was founded in 1990. Membership consists of all the mathematical societies in Europe and about 2000 individual members who joined through their national societies. This site contains details about EMS membership, projects, activities, news and provides access to several free mathematical databases, including Zentralblatt MATH.
- The London Mathematical SocietyThe Society was founded in 1865 and was granted a Royal Charter in 1965. The Society was established for the promotion and extension of mathematical knowledge. To this end the Society undertakes various publications and holds regular meetings, conferences and symposia. This site has details of membership, jobs, courses, grants, publications and a list of mathematics related web links.

- Internet MathematicianOne of a series of tutorials written for the Intute Virtual Training Suite. This tutorial aims to improve Internet information skills, knowledge of key Internet sites, Internet search skills and critical thinking skills. The links basket option provides a useful listing of sites relevant to mathematics. Another tutorial is available for Social Statistics.

- Is it a reliable organisation (eg a well known university) or a subject expert?
- Can you trust them?

**Accuracy and reliability**

- Is the information correct?
- Is the grammar and spelling correct?
- Is it complete, or are they just giving one point of view?
- Do they have their own agenda eg political organisations?
