The Internet is an excellent source for information. This month's Web site review looks at informative sites for engineers, including an Internet engineering library, a mechanical engineering-related resource, a job search for engineers, and a site discussing the theory of constraints, the thinking process and synchronous manufacturing.

www.englib.cornell.edu/ice/. The Internet Connections for Engineering Web site is maintained at Cornell University, Engineering Library. All the resources relate to areas such as engineering, chemistry and physics. On the home page, either click on a letter or scroll down the page for an alphabetically linked list of categories and topics. Clicking on a category, such as Materials Science under the letter "E," Engineering, brings up a page with links to societies, associations, laboratories and institutes, all relating to this topic. At the bottom of this page are links to Other Indexes. Back on the home page, clicking on Quality Engineering under "Q" brings up a page that has a link to the Creacon Enterprises Quality Engineering Server or another index, Yahoo: Science: Engineering: Quality Management. At the top of the home page, there are other links: About the ICE Server/Service, Other Internet Indexes and Make a suggestion for ICE. Clicking on About the ICE Server/Service links visitors to a page that briefly describes this site. Clicking Other Internet Indexes gives links to other sites relating to engineer-ing. If you want to make a suggestion or comment, then click the Make a suggestion for ICE link. This site is a good reference.

www.wb.utwente.nl/mech-surf/. This is the Mechanics Surf Web site, which has mechanical engineering-related information sources. On the home page are linked categories such as Engineering Indices, ME in General, Manufacturing, CAD/Design, Production/Process Planning, Online Education, Dutch Industry, and Usenet News Groups. A visitor can click one of the links at the top of the page or can scroll down the page. Under Engineering Indices, click on Engineering Information Guide, and a page comes up with more links that relate to design across engineering disciplines. Click The Engineers' Club, which links visitors to a site called Engineers.com. Each category has links to other sites relating to that topic. The only disadvantage to this site is that, when we visited, not all the category links were coming up. This site has some good links to other engineering-related sites.

www.interec.net. This Web site is a starting point for engineers looking for a job. On the home page there are linked categories, such as Job Search Directory, Site Information, Fun Stuff, Jobs Database and Resume Database. The Jobs Database and Resume Database were under construction when we visited. Under the Job Search Directory, click Mechanical Engineers, Chemical Engineers or Electrical Engineers. On these pages, a visitor will find a list of linked companies by corporate name or by industry type. There are also links to Temporary and Contract jobs, Salary Surveys and Job Outlook, and Other Resources. Back on the home page at the top of the page, click Engineering Discussion Forums. The site's discussion board comes up, showing questions, comments and responses to various topics. For some fun, browse other linked sites, such as Dilbert or the Gallery of Obscure Patents. To find out more about this site, click one of the links under Site Information.

www.rogo.com/cac/. This Web site provides resources and information pertaining to the Theory of Constraints (TOC), the Thinking Process and Synchronous Manufacturing developed by Dr. Eliyahu Goldratt. To learn more about TOC, click What is TOC? on the home page sidebar. On this page, a visitor can read about TOC and its three parts. For software companies specializing in TOC software, click TOC Software Companies on the home page sidebar. Clicking on What's New on CAC will bring up a page that has links to articles, chapters from books, conference information and consultants who have added TOC to their company profiles. Clicking on Other TOC Sources brings up a page with links to related Web sites, discussion groups and magazines. For a list of courses, seminars and conferences, click Conferences and Seminars. For a listing of books and tapes, click TOC Books. At the top of the home page is a link to TOC-Self Learning Tools. Clicking on this link will take visitors to the Goldratt Marketing Group's Web site, which discusses the TOC-Self Learning Program. This site can be bookmarked as a reference for TOC.

Can You Help?
This month, Quality Online visitor Nelson Simkins needs some help. Here's the query: "What is the number (PPM) of leakers ex-pected for plastic bottles filled with liquid?"

Can you help Nelson or any of our Quality Online visitors? Go to the Reader Forum (www.i-boards.com./bnp/qm) and post your quality and manufacturing problems, or see if you can help a fellow visitor.
