ebsCo host - Textbook of Nursing Science

First the most common online reference service is introduced:

EBSCOhost.

EBSCO Publishing provides access to its own journal ar-ticle database which also contains complete texts as well as the databases of other leading publishers and informa-tion providers. The circle of databases available for particu-lar libraries is determined by the license contract made by EBSCO Publishing. EBSCOhost is available on the web (see Figure 15) via http://www.lib.pte.hu/ or http://search.epnet.

com . The database is available on the computers of the Uni-versity of Pecs. The Library of the UniUni-versity made the home

use of the system possible for the student or the researcher.

To have access, the necessary adjustments which can be found on the link http://www.lib.pte.hu/databases must be performed on the home computer. The services are avail-able in several libraries around Hungary. (e.g. the libraries of higher education institutions, public libraries and the librar-ies of non-profit institutions). Searches can be made in se-veral databases at the same time.

The detailed descriptions of EBSCO journal article databas-es can be found in Appendix II.

A short description of databases is available in Hungarian, so the student, the researcher can decide on what is appropri-ate. If you want to search a single database, click directly on the database name, or select it and click the Continue button.

When you search more databases, select them from the list and click Continue. (See Figure 16)

The service called EBSCOhost of EBSCO Publishing offers full-text and bibliographic databases which are available free of charge on the computer network of the University of Pécs, including Medline. The most important communica-tion tool of Medicine is MEDLINE database, which indexes articles from over 5,000 periodicals and it was created by the National Library of Medicine. The MEDLINE database

is not full text, but it gives you the links to some articles.

Predominantly you can search English-language indexed journals, going back to 1966. The search results in a biblio-graphic description of journal articles, the most important data of the records (author, title, place of appearance, time) are presented. You can search in simple and complex ways, you can perform operations with your former searches, you can set the presentation of results and save them, further-more, profiles can be set. The complex search questions can be formulated by the Boolean search operators (AND, OR, NOT). If we do not include a ‘logical operator in the search terms, the terms are searched for as a sentence by the EBSCOhost search. The sentence can be put in quotation marks as well. If you type one word wrong, the automatic error correction offers other variations as control. Truncation and wildcards can be used in cases where the word looked for cannot be fully specified (eg, multiple endings, different spelling).

• When using a search engine, the character ? is automat-ically replaced by another character: e.g. if the search term is ne?, they will hit one of the terms included in the results, like neat, nest or next.

• During the search performed by truncation (*), the vari-ants of the searched terms can be found, for example if the search word is comput *, the results may include both a computer and computing words.

The results are numbered and displayed in reverse chronolog-ical order. The results include bibliographic records (citations), reports, abstracts and may contain links to the full text. The text of the articles are available in html or pdf formats.

Simple search

The search terms must be entered into the search box (see Figure 17 and 18). The search query can be changed in the search box itself, or can be deleted by the Delete button. To start the search, click the Search button. The search options can be added, the results can be narrowed to point to full text referred to by links, and the initial date of publishing can be set.

In the list of results the most recent literature appears first, followed by the other titles chronologically. If you click on the record, the summary will be displayed as well.

Click on an author, all the items can be displayed, click on the journal, you can browse in the issues of the journal.

You can create a folder where you save the results and / or print them out later and / or send them electronically.

A brief bibliographic description of the selected hit can be found (see Figure 19). The title of the article, the list of the author(s), the journal title, the abbreviated title, the release date, the annual number of the journal, its number of pages

and the page number of the article, the database name if you have the article in pdf format, can all be seen. In the zone on the right hand side of the screen the search can be narrowed to the full text, the release date, authors, clear cut articles, fields of science, human, animal, publication type, language, gender.

This is the world’s most widely used medical database, the National Library of Medicine created it and made it freely avail-able. It is the electronically enhanced version of Index Medi-cus. More than 4,800 journals are indexed by it in the field of life sciences. In addition to bibliographic data, more than half of the articles possess “abstract”, and where possible, the “full text” documents are linked to the list of search results/hits to be downloaded, printed or immediately saved. The difference between Medline and PubMed is that the Medline is available on the interface of the EBSCOhost within the university net-work, while access to Pubmed is possible online from any-where. However, reading the full text is only possible where academic / medical library’s computers are available, with the appropriate permissions. The database is international, but 75% of articles are in English. When using it, the “Boolean

op-Figure 16: The selection of database (s) Figure 17: Setting the search options in the Medline database

140 Textbook of Nursing Science Chapter 6 Literature Research in Nursing 141 erators” (AND, OR, NOT) linking the search questions, must be

written in capital letters. For truncation the $ (dollar) sign can generally be applied. The database is available to machines of the University of Pécs (http://www.lib.pte.hu) and to home computers (http://www.ncbi.nlm.nih.gov/pubmed).

Type the search question in the search box (see Figure 20).

At PubMed service there is an additional feature called the

“spell check”, this is an additional function that will automati-cally offer other spelling variations related to the given term in the drop-down list below the text entry. So spelling and orthographic errors can be avoided. An opportunity for clari-fication is the application of quotation marks which gets into the search technology of specialized databases from the gen-eral search engine. Further possibility is truncation, which is to enter the beginning of a word and make the search for the final versions with different characters possible. Before start-ing the search you can refine the search file. Clickstart-ing on the Limits (limiting / restricting) link, narrowing/limiting can be configured.

• Specify the type of article (e.g. bibliography)

• Set specific disciplines/ fields of science (e.g. zoology)

• Specify the type of journal (e.g.nursing)

• Precisely define the topic (such as AIDS, medicine)

• Set the type of text (for example full-text articles)

• Set the language of the article

• Narrow the target group of the topic of the article (for example, men and women)

• Age-selection (for example, children between 0-18 years)

• Define the type of text entry fields (e.g. author, title)

In Figure 21 we can see that we are searching in the topic of stroke therapy. We narrowed the search term to 23 months of age among children, in the last three years (2007-2010), Eng-lish language, and we are looking for full-text articles.

In Figure 22 we can see that 32 articles correspond to the specified search criteria and 5 of the articles have full text. The data of presentation in this database contain only the most im-portant information: title, author(s) name(s), publication data.

Figure 23 shows that from among the selected documents in our hit list only those articles are available with full text where the Free Full Text logo or the University of Pécs logo appears.

By clicking on the check box above the serial number or by clicking on the article title, the detailed bibliographical entries can be viewed. The article can be printed, you can send it in an e-mail, or you can save it onto data storage devices.

Of course, at PubMed complex searches can be done.

Click on the Advanced Search link above the search box . Advanced searches (see Figure 24) can be done by the logical combination of various search terms. Where an ad-vanced search is being utilised, a text box appears, the search term can be written there. The number of text fields cannot be expanded. The terms can be added to the search term by giving the text box and the type, the desired logical connec-tion is selected, then any number of addiconnec-tional search terms and the associated types can be specified (e.g. author, book).

Figure 25 shows that “Jozsef Bethlehem” was the name in the search box and assigned to this, the author Andras Olah.

The system automatically offers Boolean operator AND (see Figure 60). Of course, you can set some other operators as well.

Figure 26 shows that in the PubMed database 8 search re-sults are available for the authors Jozsef Bethlehem and An-dras Olah, out of them one article is available in full text. The

records are sorted by the date of uploading, the last uploaded article is at the top. Information can be obtained by the op-tions on the right hand side next to the set of results. The number of all results and statements made about the Reviews between the articles, and about the number of articles with full text (Free Full Text) can be found.

EISZ was the national program of the former Ministry of Edu-cation and Culture which allows the use of international and Hungarian information resources on the basis of a national license for students, academics and researchers in higher education, and for the staff of scientific research institutions.

Users can only have access to the databases required and where they are supported by their institutions, as the mem-ber institutions have to contribute to the subscription fee of databases available within the frames of EISZ. The database, which is a service available for the computers of the Uni-versity of Pecs, requires EISZ registration. Home use can be solved in several ways if the institution provides opportunity for this by dial-up connection, by the institutional VPN con-nection, or through (institutional) Terminal Service access.

The third option is port forwarding – this means just to have a topic number on a computer which can be achieved by the so called SSH (Secure Shell) protocol and from which the service requiring IP address can be already available.

The EISZ can be available on www.eisz.hu or www.lib.pte.

hu/database.

The system sends the password to the e-mail address given on the registration form. The user rules must be

ac-cepted after entering the user name and receiving a private password. Then the user is allowed to enter the system.

If within six months you do not enter the system at least once, the regulation of EISZ stipulates that your ID will be automati-cally deleted. In Appendix III more detailed descriptions of da-tabases in EISZ can be found.

Web of Science (WoS) is a bibliographic database pack and the citation index service of ISI (Institute for Scientific Informa-tion). It is an inter-disciplinary database, which can contribute to the whole science territory by the freshness of its material published weekly.

It standardises the material according to scientific criteria and provides multi-faceted search. In its content it is possible to search for the short summaries of scientific conferences, reports, and articles as well. (Via the Internet the publica-tion of the last five years, the archive issues can be searched and weekly updates can be downloaded onto intranet.) The citation index is exclusive to the service of the WoS which allows science metric analyses, as it also reveals the author references in addition to bibliographic data of the articles.

Figure 25: Author search

Figure 26: List of Results Figure 27: The home page of Electronic Information Services

There are three main disciplines at our disposal:

• Science Citation Index: Natural science and Technology Index, more than 5,900 journals in 164 branches are fully processed.

• Social Sciences Citation Index: Social Science Index, it re-veals more than 1700 journals of 50 science branches and the related articles of 3300 border line periodicals are also included in its service.

• Arts & Humanities Citation Index: Arts and Humanities In-dex, more than 1,100 journals of 25 branches of science are indexed, and 6800 more are reviewed for selection purposes as well.

The general rules of a search:

• Avoid making the search queries to broad. For example:

cell, behaviour.

• Both small and capital letters can be used.

• It is desirable to provide a number of possible forms of expression.

• When a phrase is in quotation marks (“”), the search is for the exact phrase. The words without quotes are in automatic AND in relation with each other. For example, “heart attack”

aims at different sources than heart attack, the latter two words can appear anywhere in the field to be searched.

• Banned words are common words that are not taken into account by the system when searching, for exam-ple: the, an, he, she, we, etc.

Truncation, the use of Wildcards:

• 0 can replace any number of characters, no matter

where in the word, in several places (except at the be-ginning of the word)

• can stand anywhere and can replace exactly one char-acter, in several places in a word

• can stand anywhere and can replace 0 or one character, in several places in a word

– Boolean operators are used in the usual way:

– AND (logical and), OR (logical or) and NOT (logical not).

Automatically there is an AND relationship between two expressions if you do not write another linking word.

Simple search in the WoS database

In this search a topic, an article title, an author, a corpo-rate author, a journal, and the author’s workplace address, the year of release, the journal title, language and document type can be searched. By default, the three search boxes appear, but you can also add additional lines (Add Another Field).

A new option is that we can connect to the Web of Science database (see Web of Science section) immediately. (Find au-thors articles in Web of Science), and it enables you to check the works of the author (Figure 28).

You can see that in the Web of Science (WoS) database the number of articles by András Olah is 39. Figure 31 shows that the articles are in descending order by date. A short descrip-tion of the article (title, author (s), journal title, publicadescrip-tion data: volume number, page number, page number can be found. The number of references to the article (Times Cited) can be seen. In the database the author’s citation index and h-index (see Figure 29) can be calculated.

Advanced Search

In this case, search terms can be linked by u ing Bool-ean operators. The other settings are the same as at simple search mentioned above. Enter the search query in the

fol-lowing manner: at topic search enter a search query in the search box and click the Search button. Example: stroke and nutrition, in English, in the time period 2007–2008 (see Figure 30):

records - 100 results in the case of relationship of quick search of the Stroke and nutrition topic in English in 2007-2008. The following illustration shows the top five hits. The detailed dis-play can be started by the check box before the serial number of the record. The fourth and fifth hits are available with full text.

After the fourth record is selected, the following is dis-played (see Figure 32) the title, author (s), journal title, year number, volume number, page number. You can see the number of references (Times Cited: 0, in this case there is not any), and literature used in the article, number of refer-ences (Referrefer-ences: 28), by clicking on it, the bibliography of the article can be seen. A full display will be visible by

clicking on the Full Text icon. The data items of the marked articles can be printed, sent in e-mail, can be added to the list of marked items (Marked List).

Science Direct is the full text database service of the sci-entific publishing house Elsevier. Its main profile is the dis-semination of scientific, technical and medical journals in print and electronic form. It provides full text access to the electronic version of its self-published paper based jour-nals and to jourjour-nals of other publishers. It allows you to search bibliographic data, and access full-text and data-base jointly. There are magazines that can be found in the database before being printed. The search can be simple, complex or browsing (Browse). At simple searches the ar-ticle title, keywords, abstracts (abstracts), author, the title of the journal or the book, the related parameters of publica-tion can be searched. Figure 33 shows the initial interface of Science Direct. On the left hand side of the front page the option of browsing (Browse) can be seen. You can se-lect an initial letter or topic / subtopic and display the list of all books and journals available via Science Direct. This includes both pre-paid/subscribed and non-subscribed journals.

By quick search even from the front page you can search for the most common criteria: title, extract / abstract word,
