  1. Start Searching Online databases step by step

  2. Start searching • Different roles are possible, we will act as intermediaries, so communication with the customer is very important. • The customer always acts (too) late, is in a hurry • “Keep cool” take your time to prepare your search actions, don’t “jump” in the system, unless you are very experienced, it will cost extra time & money and probably not give proper results • Try to understand the customer fully, ask questions if the problem/subject is not fully clear Stimulate 4, October 2004, VUB Brussel

  3. - To find the correct database you can use - Manuals, data sheets - System Help like - Quest Topic or Dialindex - Database of databases / Gale Database (Dialog) - Stimulate 4, October 2004, VUB Brussel

  7. Indexes from EAUDOC The Basic Index for EAUDOC consists of the Title (TI), Controlled Terms (CT) and the Abstract (AB). If no access code is specified then all of these codes, belonging to the Basic Index, are included in Expand and Select commands, eg S AFRIQUE means select the word “Afrique“ in the title, controlled terms and the abstract.

  26. Truncation of search terms Means that you only type the word stem (= trunc) followed by a truncation sign. (? For EINS)  The system will automatically put the likely word combinations in the "OR" relation • Right truncation For right truncation you type the first part of the search term followed by a truncation sign (this is also useful for the plural form). Examples: • Hydrolog? will result inhydrology of hydrological or hydrologically or … • Left truncation ( only available in a few systems)For left truncation you first type the truncation sign, directly followed by the last part of the search term. … • Centre truncation or masking For centre truncation you put the truncation sign somewhere within the typed search term. Examples: • Wom?n will result inwoman or women • Organi?ation will result inorganisation or organization Stimulate 4, October 2004, VUB Brussel

  27. Advantages and disadvantages of truncation • Advantages: • Using truncation saves a lot of typing • Truncation can result in word combinations which you had not thought of before • Disadvantages: • Using truncation could result in undesired information. For instance, you are interested in literature on automation and when you type "auto*" you will also find information on cars.So, when using right truncation, place the truncation sign as far to the right as possible! • Truncation signs and their denotation could differ per host.

  32. Digital Object Identifier (DOI) Digital Object Identifiers (DOI) are now available as a separate field in the following databases: Psychinfo, CAB and Global Health. The DOI will offer a direct link to the full text of e.g. journal articles via Medra, a service offered by Cineca. It is expected that in the course of 2004 more databases will become available with a separate field for the DOI. Most of the direct links to the full text have a charge or require a subscription. To see an example, please use the command e(xpand) 10/doi in one of the above mentioned databases. Stimulate 4, October 2004, VUB Brussel

  33. Search Strategy Checklist • 1. Define the topic • 2. Break it down into component concepts • 3. Decide on the words/phrases to describe concepts • Think of possible alternatives: • terminology • spelling • synonyms • 4. Decide on relationships including TRUNCATION • 5. Try out the search • 6. Display results • 7. Refine search if necessary • BROADEN • put alternatives • reduce number of linked terms • change terminology • NARROW • link terms • add terms • change terminology Stimulate 4, October 2004, VUB Brussel
