Basics of literature searching

Define your search terms

Break down your topic to its facets and find appropriate search terms

Emission of methane from liquid manure

facet 1:

emission

facet 2:

methane

facet 3:

liquid manure

5

Refining your search request

To optimize your search request also consider

synonyms, technical terms

foreign languages if applicable

different spellings (British/American)

broader, narrower and related terms

– encyclopedias and dictionaries can help!

6

Refining your search terms

emission of methane from liquid manure

facet 1:

emission

air contamination

air pollution

production

microbial degradation

• and analogous verbs

facet 2:

methane

CH4

biogas

greenhouse gas

facet 3:

slurry

liquid manure

7

Phrase searching

Phrase = search terms in exact order / exact sequence of characters/search terms

helpful if looking for composite terms

Most databases use quotation marks to indicate a phrase

‘‘liquid manure‘‘

8

Using truncation

Truncation = substituting any amount of characters by a wild-card character

the most common wild-card character is the * (but the $ is also used by science databases)

right truncation:methan* finds methan, methane, methanol etc.

middle truncation:m*ller finds mueller, muller, miller, müller etc.

left truncation:*bird finds bluebird, blackbird, jaybird etc.

some databases imply right truncation automatically

9

Boolean operators / terms

“AND”results (shaded area) contain all search terms

(A) methane AND (B) slurry

“OR”results contain at least one search term

(A) slurry OR (B) liquid manure

“(AND) NOT“results exclude search term

(A) biogas NOT (B) carbonmonoxyde

Locating journals

11

Electronic journals

journal titles, not articles

12

Print journals (+ electronic version)

13

Searching ZDB the world’s largest specialized database for serial titles, offering 8.7 million holdings information from more than 4300 German academic libraries)

keyword general: science => 17872 hits

title (keyword) : science => 14275 hits

title (string): science => 1040 hits

exact title: ‘‘science‘‘ => 16 hits = phrase search

14

ZDB – holdings information

library

call number (location on shelf)

subscription information (here: current since 1901)

here: for 4 years only

15

Relevant institution codes

Standard identifier for libraries, organizing criterion of ZDB

5 = ULB Bonn Main Library

5N = ULB Bonn Branch Library MNL

5/ ... = University Bonn, Institute…

98 = local Branch Library „Nutrition, Environment, Agriculture“ of the National Library of Medicine / Cologne

Bo ... = other academic libraries in Bonn (e.g. German Reference Centre for Ethics in the Life Sciences Bo 404)

38 = University and Public Library Cologne

38M = National Library of Medicine, Cologne

16

Access to full text electronic article via ZDB

EZB = electronic journals database

17

External libraries´ licenses of electronic journals accessible from MNL

Important for students of medicine and related fields:

Journals licensed by the National Library of Medicine / Cologne (ZBMed) may be accessed from two special computers here in MNL (requiered password obtainable at the information desk)

Identification of those journals in ZDB database only (38M). Not possible via eJournals search in DigiBib or Main Catalogue!

use ZDB-gateway

18

Checking out access via ZBMed licences (ZDB eJournals)

Retrieving journal articles

20

Looking for articles?

never in catalogues!

but in bibliographies (respectively literature databases)

as those don´t give any location information, you will have to do a subsequent catalogue search (ZDB or DigiBib) for the journal (title) that contains the required article

most databases available at ULB/MNL automatically search our catalogs using SFX (Find it@ULB Bonn, Check@ULB Bonn, Fulltext@ULB Bonn ...)

21

Using Google to search for scientific journal articles?

yes, BUT

Google doesn´t know everything („Invisible Web“)

Google searches seldom come up with the agency used by University of Bonn conditional access, fees

there is no quality control

for better results use instead

GoogleScholar (http://scholar.google.de/ with linking service SFX)

journal article databases, scientific literature databases

22

Databases and electronic journals

For those subject to license conditions there is free access for members of University of Bonn only

on campus from any computer, identification by IP-Address

from home computer or laptop anywhere via special user identification attainable from IT-center (Rechenzentrum) + VPN-Client
