Library research methods
- 1. Library Research Methods and Databases
- 2. Library Research as Research Begins with a question What resources are available to study about . . . ? Solves a problem In order to study . . . , I need to find . . . Requires skills Specialized techniques Specialized resources Leads to a discovery
- 4. Find sources of information
- 8. Analyze what you find
- 9. Outline, write, re-read, write,
- 13. Developing an Overview Preliminary reading Reference books Journal articles Internet articles Looking for Issues Personalities Context Bibliography Summary: Become oriented to the literature on your topic Virtual Reference Library
- 14. Building Blocks of Library Research
- 15. Methods of Research Key word/phrase by field Controlled vocabulary Citation searches Combinations of the two Hierarchal Browsing Types of media or literature These methods can be used with both electronic and printed repositories of information. The methods work with electronic repositories because these are all some form of database.
- 18. Searching with Keywords Keywords are usually nouns or are phrases that include nouns Islamic fundamentalism Muslim fundamentalists Keywords can also be proper names Osama Ben Laden (person) Afghanistan (place) Iraq war (historical event)
- 19. Choosing Keywords Terms you know People Places Events Words and phrases that describe your topic Terms you learn Other persons Variations in name Broader context of event Buzz words, colloquialisms Jargon, clichés Words found often in titles Words found in reading
- 20. Combining Keywords Boolean searches AND narrows a search OR combines synonyms (broadens a search) NOT excludes words from a search (narrows a search) ( ) changes order of operation (think algebraic equations) Proximity searches “enclose in quotes” With (w) or adj (adjacent) Truncation symbols ? or * Pre-coordinated subject terms
- 21. PrinciplesofKeywordSearching Think about the terms you will use OR broadens a search Used to find synonyms AND and NOT narrow a search Use NOT exclude terms, dates, etc. The more concepts you link with AND or NOT, the fewer results you will have Keyword searches promise “high return, low precision” More about keyword searching
- 23. One word or phrase used consciously and repeatedly to describe a cluster of synonyms related to a topic

- 38. Comparing the Two Approaches
- 39. Citation Searches Definition Finding the sources cited in book or journal, or finding books and articles that cite a particular source—either while reading or by using a database. Some strengths Authors generally cite sources that are related to their topic. Some articles are cited by several articles. Authors are familiar with the sources they have listed Some weaknesses Sources cited are always older than the book or article that cites them. However, the book or article citing a source is always more recent than the source itself Possibility of author’s bias in choice of sources. Learn about Citation searches in EbscoHost

- 41. Hierarchal Searching Definition Limiting results by context Advantages Quick way to narrow searches yielding thousands of results Useful with terms whose meaning varies by context Disadvantages May still yield hundreds of results Technique varies by database JSTOR : “Narrow by discipline and/or publication title” SWBTS catalog: “You found Titles in Categories” EBSCOhost: “Refine results . . . Subject” WorldCat.org: “Refine your Search . . . Topic” ATLA Hierarchical Scripture Authority index Dissertations (ProQuest): “Narrow results by . . . Subject”

Editor's Notes
- Your task is take what you know and then build a bibliography so you can later study (read) what others have learned from their research or experience. This way you will expand what you know and, at some point, learn what you and others do not know, so that you make a “contribution to the field.”Incidentally, research is simply reading, note taking, and writing. There is not much glamour to it; computers can help, but cannot substitute for these basics.
- As you begin your search for resources, remember that you are surrounded by information. At the center is you yourself: what you can recall of what you have learned and experienced, and (for our purposes) your personal library. In the United States, virtually everyone has access to an institutional library, whether at school, in the community, or even in prison. Somewhere close by, there is a library you can call “my library.”Third, in the United States, there are networks of libraries, from the local area, to the state, to the region, and throughout the U.S. (and Canada).Fourth you have the internet—not as a tool for physical exchange of information, but as repository of accessible information.
- Preliminary reading is important for library research, just as it is for other types of research. One difference is that in addition to “finding a place in the conversation,” you are also looking for clues that will help you find further information: persons, historical and social context, books, articles. You view several full text reference books at http://access.gale.com/ebooks/txshracd2553/The password from off-campus is ‘texas’.You can also connect through the Knowledge Portal by clicking on Virtual Reference Library.
- Having a clear research question gives direction and helps insure that your searches have the desired results. Understanding and using a variety of search methods builds confidence in your results.Identifying the appropriate repositories of information (i.e., databases) saves you time.
- Although these methods are often applied to electronic resources, such as journal databases and library catalogs, can also be applied to printed sources.When you scan a book’s index or table of contents you are searching for information within book using key words and phrases.When you are “chasing footnotes” or gleaning resources from a book or article’s bibliography, you are doing citation searches.Printed indexes, such as New Testament Abstracts, add information to individual records in a standardized form to help keep sources together based on common characteristics: Bible book or verse, author, etc. Controlled vocabulary is was developed for use in the library card catalogs; standard forms of author’s names, uniform titles, and standardized subject headings are all examples of controlled vocabulary.
- This is an example of an unformatted database record from the SWBTS library catalog. The “card” is a record. Each line is a field; in this type of databases, fields can also have subfields. The data is the information within the fields and sub-fields. The blue fields contain meta data. The other information comes from the book itself
- (See also Badke, 25-34)Keywords can also be phrases: think keywords or key phrases
- An advantage to keyword searching is that you are not limited to a “controlled vocabulary.” In fact, you can think of keyword searches as “uncontrolled vocabulary searches.” Basically any string of text, including numbers and foreign words, can be used in keyword searching. Title is a hyperlink to UW website that explains problems with choosing words as key words.
- The power of key word searching is that you can combine terms yourself as you create your search.What are pre-coordinated subject terms? Many controlled vocabulary terms have already been combined, or act as combined headings when placed with a subheading. In such cases, two broad terms have been combined to form a single narrower term, e.g., Religion and Television; or Baptists—Texas.
- Here are five “rules of thumb” to remember about keyword searches.1. Give some thought to the terms you are going to use. Do not rely just on the first words that come to mind.2. Use OR to combine words and phrases that function like synonyms. EbscoHost lets you combine searches you have already completed. Therefore you search for many terms related to one concept and then combine the results with a second concept to improve precision and return.3. AND is the usual default operator in database searching. This means that when you entering words in a text box, you are searching for the combination of words unless you specify OR or NOT. As you might guess, NOT is the opposite of AND, yet has the same effect on a search. Sometimes it is useful to narrow a concept by excluding terms.4. Since you are combining terms, each term you add with an AND or NOT further restricts the search. If you have several terms connected by these two operators, and have few results, do the search again omitting one of the words.5. “Return” refers to the quantity of search results; “precision” refers to the quality of search results. Experienced searchers strive for a good balance of the two by their choice of words to use and their choice of logical operators to use.Click on blue for some good advice from the librarians at the University of Washington.
- The definition may not be the best available. How does Mann define “controlled vocabulary”?Authors and publishers use a wide range of vocabulary as titles; this show another reason why you “cannot judge a book by its cover [or title page].” 2) Subject headings can also serve as a broad summary of the book’s contents. However, most book records are assigned only two of three of the broad headings to indicate the content of the book. 3) The pattern of construction has been the subject of attention in the library literature, so it is obviously not an easy matter to explain or learn. One pattern you will often see is that when you have a noun phrase, the noun comes first, followed by the adjective. Another is that when you have two nouns in a heading, the one with broadest meaning (or most commonly used) comes first. Why would these be considered logical? 3.a.) For seminary studies, another valuable feature of set patterns of construction is the consistent ways books and parts of the Bible, personal names, and geographical places are treated—these are patterns that you can, and should, learn (and that we should teach). 4) Libraries in the U.S. and Canada practice “shared cataloging.” This means that almost all libraries use one set of terms as their “controlled vocabulary” and that the headings chosen by the first library to catalog the book are the headings that most other libraries will use, too. Because of the Library of Congress’s “Cataloging in Publication” program, which dates from the early 1970s, staff at the LC will assign the headings. Sidebar: CIP is cooperative arrangement between LC and publishers; the publishers send to LC the galley proofs prior to final publications. This is why you will often find the cataloging information printed in the book itself or information in WorldCat or the LC online catalog before the book is on the market. Weaknesses, which do not outweigh the strengths, are mostly related to the fact that this process is an “art,” not a science. The process requires human judgment which is influenced by a large number of factors [what are some you would you guess?]. It is also an expensive process—especially for the Library of Congress and the U.S. taxpayers. The leadership at the Library of Congress is seriously considering abandoning the practice in favor of computer generated lists based on keywords. Do you think this is a good idea? For one view see Thomas Mann’s recent article "Research at Risk“. 2) a second weakness is that the terms listed in the controlled vocabulary are not always those that are in common use, either because of the way they are constructed or because of how the language has changed. LC will update the headings, but few libraries will make changes to their catalog. Also, just as those who assign the headings need an understanding of the subject area, those who use make the best use of the headings need to an understanding how the headings are created and applied.
- The next few screens show headings used for some of the books in my office library. Notice the vocabulary, the patterns. When looking at individual titles it is easier to see the weaknesses. When looking at the headings in a library catalog, it is easier to see the strengths. The first part heading is the “main heading”; the second and third parts are “sub-” and “sub-sub-” headings. What observations can you make about the sub (and sub-sub) headings?
- Remember that the headings were originally, and still primarily, developed for the Library of Congress’s holdings. For a seminary library, the term ‘Preaching’ by itself is usually too broad to be helpful for its users. However, for the Library of Congress, it would be adequate.
- The use of Staley as a personal subject heading may be an error. The book is not his autobiography but is based on his research based on autobiographies written by pioneers, etc. in the settlement of the western United States. How does the use the single main heading “Bible” differ from the use of the single main heading “Bible. N.T. John”?
- Here we are introduced to the adjective ‘Biblical’ as part of a heading—as well as the omission of explicit reference to the Bible in a heading for a book about a part of the Bible.
- In my opinion the most important point to remember about using controlled vocabulary in library or journal database is “click on blue.” This is short-hand for the older version “if you know one book or article on your topic, see which subject headings have been assigned to it, and then use those headings to find other books with those same headings.In computer catalogs, these subject headings are hyperlinks that take you to a list of items that have been assigned that heading.
- I have circled the subject terms. Notice that author and title are also hyperlinked. This lets you find other books by the same author or other editions of the same work. Technically, authors’ names are another form of controlled vocabulary since librarians also use standard forms of a name to insure uniformity and uniqueness.
- Controlled vocabulary lists have an internal structure to show the relationship to other terms in the list. These will sometimes be incorporated into the search results.Used For and See both refer you from a term not on the controlled vocabulary list to a term that is on the controlled vocabulary list. Broader Terms refer to other terms on the list that are considered broader than the one you used.Narrower Terms refer to other terms in the list that are narrower than the one you used.Related Terms refer to other terms in the list considered similar to the one you used.See Also usually refers to broader, narrower, or related terms in addition to the one you use.
- These two lists review why using both approaches when searching for information is to your advantage, compared to using one or the other.High recall is librarianese for a search that has a large number of results. Low recall describes a search with few results.High precision means that most of the search results are precisely what you are looking for. Low precision means only a few of the results are relevant.By practice, and by using several search terms, some can achieve high precision/high recall or high precision/low recall. Most of use are content with high recall/low precision and then sort through the results manually, making selections with our brain instead of with someone else’s computer program.
- Information comes in a variety of formats: printed books, popular magazines, newspapers, peer reviewed journal articles, dissertations and theses, lectures and documentaries recorded on DVDs—to name a few. Library catalogs and larger databases, such as EbscoHost and WorldCat do not limit their contents to one particular format. Instead they add a descriptive term that distinguishes the different formats from each other. Usually “media type” is given as an option on the advanced search page.Some information is better suited for some media types than it is for others. Newspapers: current and past events and related opinion columns; local information, trends, etc.Popular magazines: current and past events, photos (usually copyrighted), opinion columns, overview of current topics or issues. Most popular magazines are written for a specific market or audience, e.g., Christianity Today is written for those interested in evangelical Christianity.Peer reviewed articles in journals are written for specialists and have been recommended for publication by experts in the subject.Dissertations deal with one topic in depth, surveying the background and providing an extensive bibliography.Web pages can be almost anything, published by anyone. Prefer sites that have domains such as .gov, .edu., .ac, .org, .net over the .com domain.
- Use this search technique to complement key word or controlled vocabulary searches.
