Learning Objectives By the end of this session you will be able to: Understand the relationship between journal literature and online databases Identify and locate articles in both electronic and print journals Use the databases Web of Science and PubMed to carry out literature searches and access full-text content October

INTRODUCTION TO JOURNALS

Journals  Also known as periodicals or serials  Print and electronic formats  Four reasons to use them: A rich source of current research information Specific and detailed coverage of subjects Peer-reviewed Recommended by your lecturers October

Journal Literature: Search Tools  Library Catalogue  Articles Search  Online Databases October

Locating a Specific Journal Article Example Reference  Flory, J. et al., Low temperature assembly of functional 3D DNA-PNA- protein complexes. Journal of the American Chemical Society, 136(23), pp. 8283–8295. October

Locating a Print Journal October

INTRODUCTION TO DATABASES

Databases: what are they?  Searchable indexes of evaluated literature such as journal articles and conference proceedings  Types of database:  Bibliographic indexing & abstracting databases or full-text collections  Subject-specific or interdisciplinary  Use to carry out literature searches October

Databases for Biochemistry October Indexes to the published literature (and more)…

Major search tool comprised of 3 indexes that provide multidisciplinary coverage of academic literature (Science Citation Index, Social Sciences Citation Index, Arts & Humanities Citation Index). The Science Citation Index covers almost 7000 journals from 1952 onwards. Web of Science was formerly known as Web of Knowledge October

Allows you to search Medline for unparalleled access to the worldwide biomedical literature, including more than 4,500 journals. It contains a broad range of medical topics relating to research, clinical practice, administration, policy issues and health care services October

Accessing Biochemical Databases As a Biochemical students you can access relevant biochemical resources via the Discovery tool or the Library’s subject support webpages for Biological Sciences and Chemistry: October

SEARCH TECHNIQUES

Preparation  Developing a search strategy  Selecting an appropriate database e.g. Web of Science  Combining search terms – AND, NOT, OR October

DEVELOPING A SEARCH STRATEGY

Developing a Search Strategy  You should by now have a topic for your research. How many words and short phrases can I find that describe the subject in both its broadest and narrowest terms?  Spend a few minutes now writing these words and phrases down! October

Developing a Search Strategy  Identify important concepts and choose keywords  These will include synonyms e.g. influenza, human influenza, flu, grippe  and related terms e.g. orthomyxoviridae infections October

Truncating Search Terms  Many information resources allow you to search for the beginning of a word plus any ending using the symbol * E.g. develop* will find developing, development, developmental October

Phrase Searching  To search for an exact phrase, enclose the phrase in quotation marks  For example, the query “Biochemistry of Metabolism" will retrieve records that contain the exact phrase biochemistry of metabolism. October

Combining Concepts Consider how to combine concepts - using the operators AND, NOT, OR - using specific search fields October

Boolean Operators AND enzyme AND catalysis Search for articles that contain both of the search terms. Using AND narrows your search OR enzyme OR catalysisSearch for articles that contain one or both of the search terms (useful for synonyms). Using OR broadens your search NOT enzyme NOT catalysisSearch for articles that contain the first term and do not contain the second term. Using NOT narrows your search October

Asimov AND cat Boolean Search String Game Did aliens write Asimov’s thesis? Isaac Asimov: A life of Science? Asimov OR Science Asimov NOT Crater September Asimov’s stray cat

SEARCHING WEB OF SCIENCE & PUBMED

Exercise 1 Van Zeist, W.-J. & Bickelhaupt, F.M., The activation strain model of chemical reactivity. Organic & biomolecular chemistry, 8(14), pp.3118–27. Use Web of Science to find this journal article and answer the following: 1)How many references are cited by the authors? 2)How many times has the article been cited? 3)Can you access the full text of this article? October http://

Exercise 2 You want to find journal articles about avian flu and have jotted down the following keywords: bird, avian, flu, influenza. You are not interested in information relating to vaccinations against avian flu. Use PubMed’s advanced search builder to construct a suitable search and answer the following: 1)How many results do you retrieve? 2)How would you then refine this search to articles dealing with avian flu in humans? October http://

TROUBLESHOOTING YOUR RESULTS

What to do if you only get a few results?  Include all possible synonyms. Use a thesaurus to find alternative terms that describe the subject you are researching  Use broader search terms October

What to do if you only get a few results?  Spelling – If you are using a US database you may need to use either US spelling or wildcards such as ? to replace the letter that is different in each spelling. E.g. to search a US database for organisations you could use the US spelling organizations or type organi?ations into the search box  Snowballing – If you find one relevant reference you can use it to help you find others. Check the references and bibliography at the end of the article for related works  Truncation – E.g. microscop* October

What to do if you get too many results?  Build a more specific search using additional search terms linked with AND between each term  E.g. if you wanted to find references about cancer immunotherapy especially concerned with cytokine therapies, type cancer AND immunotherapy AND cytokine October

What to do if you get too many results?  Exclude irrelevant subjects by typing NOT before the term you wish to exclude  E.g.: if you wished to find references about cancer immunotherapy, but not those about cytokine therapies, you might use immunotherapy NOT cytokine October

What to do if you get too many results?  Use the search fields to limit your results by date range. E.g. if you were looking for the very latest research on a particular subject you could type in the date field of the search options  Limit your search to particular fields, e.g. enter your search terms in the title field of the search options October
