Extractions: What other tools exist to find information through the Internet? Finding the Web documents (a.k.a. Web "pages" or " sites ") you want can be easy or seem impossibly difficult. This is in part due to the sheer size of the WWW, currently estimated to contain 3 billion documents. It is also because the WWW is not indexed in any standard vocabulary. Unlike a library's catalogs, in which can use standardized Library of Congress subject headings to find books in most large, general libraries in the U.S., in Web searching you are always guessing what words will be in the pages you want to find or guessing what subject terms were chosen by someone to organize a web page or site covering some topic. When you do what is called "searching the Web," you are NOT searching it directly. It is not possible to search the WWW directly.

Extractions: Develop a subject search strategy Decide where to focus your search ... Newer References REASONS FOR SEARCHING There are differing needs that necessitate searching and using the scientific literature. Each requires a slightly different process and the use of a somewhat different set of information tools. Current Awareness - keeping current and informed about new literature and current progress in a specific area of interest. This is done in a number of ways, both informally in communications with colleagues and more formally through sources such as those listed in Current Awareness in the Sciences . You can also use Databases available to HSU students and faculty to do a subject search of current literature added to a database. Some allow you to save a search profile that can be run periodically against new records in the database.. Everyday Needs - specific information needed for experimental work or application of scientific understanding. It may be collaborating data, a method or technique, the construction of experimental apparatus, a mathematical equation, an explanation for an observed phenomenon, or other similar needs. Locating the information needed in the daily work of scientific research can take a great of time. Informal communication with colleagues is a major source for meeting these needs.

Citing Electronic Resources With more than an estimated one billion documents already available on Internet, finding relevant information can be quite tedious. The the ability to identify, select, and evaluate information is an important new skill to learn. Selecting a Search Tool If you're researching a reasonably common topic with a reasonably common theme, use a general index (a site that divides pages up into categories, like Yahoo!) before you use a general search engine (a site that indexes every word of every page it catalogs, like Alta Vista). If there's one available, use a topic-specific index before you use a general one. For example, if you're researching vitamins, you'd want to use a health index like Achoo For a comprehensive ONLINE resource about searching check http://searchenginewatch.com/facts/major.html There are essentially three categories of search tools: Directories/Index Directories are like card catalogs.

Extractions: "Every search engine will give you good search results some of the time. Every search engine will give you surprisingly bad search results some of the time. No search engine will give you good results all of the time." Don't get frustrated if your search isn't yielding the results you'd like to see. Try another angle. The purpose of this page is to pass on the knowledge we've gained about searching specifically for historical information. Anyone who's "surfed" a bit can tell you than often your search yields very little actually related to the topic which you intended to pursue. The reason many of us stay up until three o'clock in the morning is that even the "misses" in a search can yield incredibly interesting sites. You get involved clicking into a beautifully designed site, oohing and aahing at stunning graphics, reading fascinating accounts of people who have nothing to do with your paper topic, and soon it's time to get up for school! Well, your time is precious. You need to decide how much time you are willing to spend searching, then proceed to more structured finding aids.

Extractions: Updated: 19 November 2003 Reaction chemists are interested in a variety of information when planning a synthesis. That may include the conditions under which the reaction is to occur, the starting materials and reagents, catalysts, reaction sites, yields, products, by-products, functional group transformations, bonding changes, and mechanisms of the reactions. [A reaction MECHANISM is "a detailed description of a particular reactant to product path, together with information pertaining to intermediates, transition states, stereochemistry, the rate-limiting step, electronic excitation and transfer, and the presence of any loose or intimate electron ion pairs." (Ash, 1985)] A combination of some or all of these concepts may provide a path to the needed information, depending on the secondary source that is used. Once a compound has been synthesized, a variety of analytical and physical property techniques may be used to verify that the correct substance has been made. One way to search for reaction information is by the name of the reaction. That may be a more general name, such as a substitution reaction, or it may be an eponym from the name of the chemists(s) who first developed the synthetic method, such as the Curtius Rearrangement Reaction. Other search systems have developed around codes for various key features in the reaction.
