Websites You Will Want to Bookmark

Useful websites is the theme of the 2004 Reader’s Resource. We’re certain that you will find interesting, helpful, and indeed useful entries in the accompanying list of sites. The selected material is diverse, partly because of the subjective search criteria and partly due to the ad hoc search methodology. If you know where to look on the Internet, chances are that what you seek will be what you find. Of course, that is the problem: knowing where to look. Finding things is the role filled by an increasing number and variety of search engines. According to the searchenginewatch.com site, 41% of visits to product websites in 2003 originated from a search engine. Using a search engine is by far the most popular way to find information.

Initially, I used Google with keywords useful electronic websites. In time, useful was replaced by interesting, important, unusual, and essential. The results were very good, but eventually I found I was returning to the same major sources.

For example, www.eevl.ac.uk/, the Edinburgh Engineering Virtual Library, is a U.K. gateway to more than 150 useful engineering sites. Each of these may provide a large number of white papers, datasheets, and links to yet other sites. Often, collections of sites are maintained by colleges and universities or their departments and faculty members.

Other recurring sites were associated with bitpipe.com listings. For example, whitepapers.americasnetwork.com/ data/web/amnet/amnet_index.jsp accessed white papers from more than 70 online research libraries, but so did many other seemingly independent sites. So, although it appeared that there were several sources of information, actually there was one: bitpipe.com.

I tried Yahoo! next. The catalog style may have been more appropriate to this exercise than Google’s approach because I could progressively fine-tune the search. Given that useful websites was such a nebulous topic, I didn’t know in detail what I wanted to search for. Yahoo! presented its material in a structured manner that helped me to better understand what types of things were available.

Without turning the article research into an exercise in search-engine comparison, I also dabbled a bit in meta search engines. These entities issue commands to several actual search engines, such as Google and Ask Jeeves, and report back the findings.

One that I tried was Kartoo.com, which uses a graphical format to depict the relationships among several items. Linking lines and keywords show subgroup associations within the search engines’ findings, helping you to better define your search criteria.

The Listing

As mentioned, there are several high-level sites that reference other collections of information or lists of libraries. Standards organizations are included, and many standards can be obtained free of charge from these sites. Generally, IEEE sites only contain abstracts of papers and standards, and unless you are a member of the institution, you must pay for the full-text download. A major exception is the Get IEEE 802™ program at standards.ieee.org/getieee802/index.html. Through a partnership with industrial sponsors, all of the 802.xx standards are available free at this site.

Besides standards, the listing contains references to individual white papers, complete online textbooks, and an acronym dictionary. Subjects include ATE, algorithms, Ethernet, Wi-Fi, instrumentation, ATM, environmental testing, WAN, xDSL, and network protocols. There’s even a map of the Internet.

Perhaps the most arcane material is found at micro.magnet.fsu.edu/creatures/index.html, a photo exhibition of curious creatures and designs etched into commercial silicon chips. Similar to the graphical marginalia added to medieval manuscripts by creative monks, these embedded drawings say much more about a chip’s designer than about its electrical function. Enjoy your browsing!
