Some Types of Information Sources



Syllabus Focus: Unit 1 Module 1 Content 8Specific Objective 8: discuss various types of information sources;Content: Types of information sources: including books, journals, catalogs, magazines, newspapers, online libraries, CD-ROMs, DVDs, electronic databases, web sites, people, blogs, wikis; advantages, disadvantages of information sources.Types of information sourcesPrimary vs. Secondary SourcesThere are two kinds of sources for information, primary and secondary. Primary sources are firsthand, "direct from the source" information. Secondary sources are analyses of primary sources. If you write an autobiography, that's a primary source for your life. If someone reviews or writes a criticism of that autobiography, then that's a secondary source for your life. Or if someone writes a biography of you, that would also be a secondary source.For literature, the works by an author are primary, and the criticism of the works are secondary.For historical issues, letters, diaries, and contemporary accounts are primary sources, while anything written after the event is a secondary source.For the sciences, the output from the original research on the issue (an article on a survey conducted or the study done) is the primary source, while any analysis or summaries of research done by others is a secondary source.Books vs. PeriodicalsBooksWritten information can also be divided into two other forms, books and periodicals. Books themselves come in different types. Monographic books, a.k.a. monographs are "written once," or are books that stand on their own, rather than being part of a series. But not all books follow the monographic format. Some are actually a collection of essays or articles, written by different authors. And while the articles are related somehow, the issues within the articles can be much more focused on a smaller aspect of the issue.And occasionally you will find books that just cite sources of information on an issue, called bibliographies. Bibliographies are either comprehensive for a particular issue (within a particular date range), or attempt to be selective, just citing the "best" sources of information (again, within a date range), but most bibliographies in book format are comprehensive.?PeriodicalsPeriodicals are any written information that comes out periodically. (Hence the name.) Newspapers, magazines, and journals are all periodicals. The articles within periodicals tend to be more specific or about certain aspects of an issue, versus monographs. Periodicals take many forms.Newspapers usually offer articles that are factual accounts of events, but they can be an analysis of trends or issues as well. Newspaper articles usually aren't written by experts in the field and don't offer suggested readings or sources of where they got their information. Newspaper articles are great for current events and primary source material. Popular magazines are the least scholarly and are mainly for entertainment. Articles tend to offer general tips or advice, or interviews with celebrities.Examples: Good Housekeeping, GQ, People, Road & Track, Vogue, etc.? Trade magazines are those published by associations and/or aimed at practitioners in a particular field, offering mainly practical, how-to articles, or news useful to the field. If the magazine looks like it might be scholarly, but the articles within are clearly not, then it's probably a trade magazine.Examples: Advertising Age, Computerworld, Progressive Farmer, etc.? News magazines are more similar to newspapers, in that they offer factual, current events news and analysis.?Examples: Economist, Maclean's, Newsweek, Time, etc.? Opinion magazines only offer analysis of issues and trends, sometimes with a political agenda. Examples: Christianity Today, The Nation, National Review, New Republic, etc. A journal is the name given a periodical that is scholarly in nature. Articles are written by researchers or academics and should offer citations to sources consulted. How a particular article winds up in the journal depends on the kind of journal it is.? Scholarly vs. Non-Scholarly/PopularPopular sources of information are meant for a general audience, who are not necessarily experts in the field. They are presented in such a way that anyone can get a general idea of the information being presented. Scholarly sources of information are meant for a more specialized audience of experts in the field. There are a number of criteria you can use to determine if something is popular or scholarly- The treatment of the topic, or writing style Scholarly Tend to deal with very specific topics Long in-depth articles Are usually original research Uses technical language or jargon Popular Tend to deal with more broad topics Short overview articles Not original research Uses plain everyday language Authors ScholarlyExperts in the field (Scientists, doctors, professors...) PopularJournalists, not necessarily experts (magazine staff, freelance writers...) Audience, or who is the information written for? ScholarlyScholars, researchers, practitioners... other members of the field PopularGeneral public. Any one can read the material and understand it. Publisher: ScholarlyOften a scholarly or professional organizationPopularCommercial companies Editing: ScholarlyPeer-reviewed / Refereed - edited or reviewed by other experts in the field. PopularNOT peer-reviewed - edited by one editor, or editorial board, for readability and popularity, they are not necessarily experts in any field other than journalismDocumentation: ScholarlyDoes include References or Bibliography. Often several pages of references.PopularNo references. Sometimes mentions of experts, but no bibliographies.Appearance: ScholarlyPlain covers, few pictures - maybe some graphs and charts, matte paper, few if any advertisements. PopularGlossy covers, lots of color pictures, lots of advertisements Reference vs. General CollectionAnother dichotomy in information sources is reference sources vs. general collection books. Reference works are those resources that you only want to "refer" to a small section of the work, either to find a quick fact, or to get a general overview of an issue. The information sources found in the reference collection vary widely, but here are some common ones. Encyclopedias are the best sources for reading an overview of a topic. There are both general encyclopedias, which try to summarize all knowledge, and subject-specific encyclopedias, which focus only on a general topic like health or the environment, and offer overviews of aspects of the general topic. ?Most subject-specific encyclopedias will also offer a short bibliography or suggestions for further reading. Dictionaries offer shorter definitions and summaries of terms. Like encyclopedias, dictionaries can be general or subject-specific. Also, just to make it even more confusing, some reference works are entitled Dictionary of something, but are in fact encyclopedias in terms of scope and length of the entries. Handbooks/Manuals/Guides are works that offer quick facts, formulas, equations, or names and addresses for a particular subject.? Atlases offer information in cartographic form. While you may think of atlases as just offering maps of countries or U.S. states, some atlases describe historical events or social issues in map form, e.g. the changing borders of European countries, or the percentage of people in poverty around the world.? Print vs. ElectronicAnd finally, there's print vs. electronic information. Like print, electronic information encompasses all the formats mentioned above. You can find electronic books, electronic periodicals, electronic reference works, etc.?But print is not dead, for a variety of reasons.?Publishers themselves have been somewhat wary about going completely digital, and some of them package the electronic versions with purchase of print copies.? Libraries have centuries worth of print information, and a lot of it is not going to be digitized anytime soon, if ever, simply because it wouldn't be profitable to digitize it.? Some types of information don't lend themselves to being read on a computer because of the current? technology, and it isn't cost effective for individuals to print out the information.? Most e-books, e-journals, databases, and online encyclopedias are not free. The library purchases them, then gives free access to their patrons who have paid for library resources, either tax dollars for public libraries and/or tuition to academic libraries.And then there are all those free websites. There's a lot of useful information out there in cyberspace, as well as lots of unsubstantiated, worthless information as well. You can find information on any topic, assuming that someone bothered to create the website. So why would someone take the time and effort to put the website together?For commercial enterprises, they bothered because they want to sell you something, or they want to attract your attention to bring in advertising revenue.For mainstream news organizations or publishers, they are already set up to make money via advertising, so they may be able afford to offer free content. But they may only have a week's worth of articles available, or selected articles to entice you to subscribe. For federal and state government agencies, they have a legal mandate to disseminate information gathered via tax dollars back to the public. So the Internet is seen as a cheaper method of dissemination than print. For non-profit organizations, they want to "get the word out" about their cause, so the Internet is a perfect medium to distribute their own reports. Scholarly information generated by academics can be found, but we are still in the infancy of the Internet being used for this. There have been a number of big pushes to have more e-journals, to counteract the costs of scholarly journals, especially in the sciences. And there are a number of digitization projects of historical, primary documents on the Web, many of them sponsored by academic institutions. Some Types of Information SourcesEncyclopediasProvide a useful starting point for authoritative information. May cover a wide range of subjects or a specific subject area. In high quality publications, entries are usually written by an expert. Useful to gain an understanding of different aspects of a topic, related issues and associated concepts. DictionariesProvide definitions of terms. Are particularly useful when dealing with terminology specific to a subject area (e.g.. A concise dictionary of business). Meanings are useful in understanding how a word is commonly used. Provide synonyms - useful in ensuring comprehensive keyword searches. The Library holds dictionaries in print and electronic form. BooksMay provide a good overview of a topic. The information contained in books at the time of publication is rarely less than 12 months old. If currency is important, note carefully the date of publication and check other sources such as recent journals. Books are sometimes referred to as "monographs". Books vary considerably in the complexity and reliability of information they contain. JournalsKnown also as serials, magazines or periodicals. Provide details of the latest research and developments in an area. May be useful for tracing an idea through from its conception to the current day. Are published on a regular basis. Generally contain articles on specific topics. Some also contain short news items, letters and classified advertisements. May be classified as scholarly, trade or popular. A scholarly journal is usually written by and for experts in a field. Many scholarly journals are peer reviewed - which means the articles are evaluated and reviewed by other experts before publication and can be relied upon to be of high quality. Trade journals are published for a particular industry group and should be evaluated in this context. Popular journals range from general interest publications such as The Bulletin to those focusing broadly on a particular subject area such as Scientific American. These are not peer reviewed. It is essential to evaluate information in journals, including sources. NewspapersContain information that is very current, usually reflecting public interest and reaction, but which often goes out of date rapidly. Newspapers may have a specialised focus or audience (for example the Financial Times or The Land). Vary in reliability, with broadsheet newspapers (e.g. the New York Times or The Australian) generally considered more reliable than the tabloids (e.g. Britain's Daily Mirror). Broadsheets are likely to focus on political and economic content. Some newspapers have a particular political bent or are used as propaganda tools. Apply evaluation criteria when reviewing information from newspapers and magazines.The InternetThe Internet provides a vast amount of information with a diverse range of complexity and reliability. A web site can be created by a child, a government department, or a person or organisation with a stated or unstated agenda or bias. The Internet provides a wide range of high quality information that is widely and freely available. Information provided by government departments and reputable organisations and institutions can be highly valuable. Information on the Internet may be current to the second - but this is not always the case. Information from the Internet should always be evaluated according to criteria particularly applicable to that source. Government PublicationsGovernment publications, can be an authoritative source of high quality information such as statistics, reports, plans and activities in most aspects of scientific, economic and social activity. Much government information is now published on the Web but a wealth of valuable information is also available in print or on microfiche. Some government information can be biased depending on the political climate of the country publishing it.Conference ProceedingsRecent conference proceedings are a source of information about recent research and developments in an area. They can usually be relied upon as presenting authoritative information. Over time, useful for tracing the development of an idea. ExpertsExperts in a field will often use the Internet to discuss and debate issues. Experts are also available for consultation at the University, in industry, business and special interest groups. Online and offline, self professed "experts" are readily available and willing to provide information and advise on almost any topic imaginable. While much valuable information may be available, it is extremely important to know what credentials a person has to deem themselves an expert and what institutional or organisational affiliations they have. You should be able to find support for their ideas by other reputable people or organisations with knowledge of the topic. When consulting a subject expert always make sure you have done comprehensive research on the subject first - this allows you to ask valuable questions and make the most of the time you have with them. ................
