Finding a topic for a Bachelor's thesis or Master's thesis can be difficult. There are several ways to get inspired:
Many lawyers, academics (researchers, professors, PhDs) or law firms are writing blog posts about the current legal debate, law developments, recent cases and more.
Find a law blog with Blawg (directory of blogs on law) by category, country or law school. Or find a blog with Google: search for ‘blog’ or ‘weblog’ in combination with a topic, e.g.: (blog OR weblog) "comparative law" (N.B. results may vary).
Reading a newspaper can also be inspirational for finding a topic. Especially concerning the area of tension between society and law. Use Nexis Uni to find (old) newspaper articles.
UvA Scripties is a service through which the University of Amsterdam enables worldwide digital access to the theses (master/bachelor) of its students.
Practising scientists and (prospective) scholars need to be scrupulous and the resources they use must be reliable and verifiable. See also the Netherlands Code of Conduct for Research Integrity 2018 (ENG / NL).
Always check if a resource or information is trustworthy:
Always check whether the information is up to date:
When using information from a blog, webpage or database, always read the ‘About’, ‘Info’ or ‘Disclaimer’.
Next to a simple search, most databases and catalogues offer special characters or advanced search tools that you can use to enhance your search result when you have too many or limited hits.
1) Before starting a search, always make sure that the catalogue or database covers what you are searching for (period, document type, topic). See About, Info etc.
2) Always read the Help section before you start a search; find out what ‘tricks’ or tools are available to improve the search result.
Using quotation marks or a ‘phrased search’ commands the search engine to group the entered terms. E.g. a search for “fair use” or fair use in the UvA CataloguePlus differs in over 400 (irrelevant) hits. Quotation marks and other special characters can also be used in e.g. Google or Google Scholar.
Advanced search fields often offer the possibility to combine the various search keys (title, subject, author) with AND, OR or NOT.
AND: both terms have to be in the search result (limits the result)
OR: one of the terms has to be in the search result (expands the result)
NOT: exclude a term from the search result (specify the result)
Furthermore, it is often possible to limit or restrict a search on document type, time span, language, location, availability and more.
‘Wildcards’ or ‘truncation’ can be used for differences in languages (U.S. or U.K. English), plural or word variations.
Wildcards (?, # or !): replace one or more characters
e.g. humo?r will find both humour and humor, organi?ation will find both organisation and organization
Truncation (* or ?): begin or end a term in various ways
e.g. comput* will find computing, compute, computer etc.
N.B. characters and function may differ for each database or catalogue.
When combining search terms with AND, both terms have to be in the search result. This does not necessarily put both terms within context. One of the terms can be in the title of an article, the other in the last paragraph or even a footnote or bibliography.
‘Proximity search’ commands the search engine to search for the terms within a range; in the same sentence, paragraph or amount of words.
In Westlaw search terms can be combined with /s or /p to make sure the terms are found in the same sentence or paragraph. E.g. “fair use” /p Google.
In HeinOnline both search terms must be within a range of 15 words with the command: "fair use google"~15.
A thesaurus is a controlled hierarchic list of (subject) terms. Thesaurus terms are connected to articles or books by a specialist (e.g. librarian) to identify the content. Browse a thesaurus and click on a term to find all articles connected to the term (independent from the actual words in the text).
A thesaurus allows you to specify or broaden a search or identify subject terms. Combine the search results of queries based on a thesaurus with the function Search History (if available).
A classification is an (alpha)numeric hierarchy of subjects used to classify books or other items. It is usually broad (rough) and is used to group items together that are relevant to the same subject. Classification is closely related to library placing systems.
HeinOnline, Westlaw, Rechtsorde and other journal collections offer access to digitized or digital articles. Note that not all (older) publication years of a journal have to be included and usually the coverage of each journal varies. Some law journals are not included at all because they are not available digitally.
A bibliography contains references to or an overview of articles or books, usually not linked to availability. Bibliographies can be edited – with added keywords, topical index and/or references to legislation - or plain indexed. They can be used to find references to (old) journal articles. Next step is to find the paper journal or digital article.
700.000 references to articles - with added keywords, abstracts and legislation - published in Dutch law journals and compilations. From 1972-recent. Access via Rechtsorde (Dutch database).
Catalogue of the libraries of the European Commission. Contains book information and references to journal articles, legal materials and websites related to European Union law.
Legal Journals Index
A journal abstract service listing key articles from the UK and Europe's leading legal journals.
With keywords, cited cases and links to full-text articles when available. From 1986-recent.
Peace Palace Library Catalogue
Find books, references to book chapters and journal articles - classified with subject headings - in the field of public/private international law and foreign national law.
Public International Law
Current bibliographic information on articles spanning all aspects of public international law that have been published in journals, yearbooks, and commemorative compilations. Paper version available from 1975-2013.
Contains materials from more than a thousand libraries all over the world, all fields of science and in various languages.
The UvA-linker tells you at once if and where an electronic or print version of the article can be found. It matches bibliographic data with (paid) access to a digital version of the publication, or with the paper version in the library (or other libraries in the Netherlands).
The UvA-linker is available in UvA CataloguePlus, but also in Google Scholar (when used within the UvA domain).
A method to find older articles on a law topic is by using the ‘snowball method’. Start with an authoritative article (key article) on a topic, use the references to find older articles on the same topic, and so on. Some databases - e.g. HeinOnline and Google Scholar - offer the function 'cited by'; this can be used to find (forward in time) newer articles that have cited a specific article.
It is possible that a journal name is abbreviated in a reference to an article. For example:  2 C.M.L.R. 40 or JutD 2011, p. 21-24 (afl. 5).
Sometimes it is necessary to know the full journal name in order to find the article (see the guide Legal literature).
1) Use the Cardiff Index to Legal Abbreviations: search for the meaning of abbreviations for English language legal publications, from the British Isles, the Commonwealth and the United States and even a wide selection of major foreign language law publications.
2) Rechtsaf.be (KU Leuven) is the online version of the official list of abbreviations for Belgian journals as published in Juridische Verwijzingen en Afkortingen (Belgian style guide for referencing). It also provides links to lists of abbreviations for Dutch, German, French and UK-US journals.
3) For Dutch abbreviations (e.g. found in Data Juridica) use the Wolters Kluwer afkortingenlijst (pdf). Use the key combination CTRL-F to search the list quickly.
Both Westlaw and HeinOnline offer a ‘citation search’. In Westlaw it is possible to enter a citation in the search box on the home page. In HeinOnline the Citation Navigator can be found in the Law Journal Library by clicking the Citation tab. Note that the results may vary.
Legal sources (e.g. books, articles, case law, directives, treaties) used and consulted for writing a legal text must be cited in a clear, consistent and familiar way. The reader must be able to identify and retrieve the used resources and the writer shows that he is reliable and makes his work verifiable. Sources must be cited in a consistent way and preferably according to a uniform citation rule.
Software is available to make citing easier, the so called reference managers.
How do you cite correctly and when do you speak of (self)plagiarism? The KNAW advisory memorandum (pfd) can be used as a guideline and judgment in specific cases.
In the ‘Regulations Governing Fraud and Plagiarism for UvA Students’ you can find out what the UvA defines as fraud and plagiarism and which rules you must follow when taking an exam or writing an essay or paper.
Common styles used for English legal texts are the Oxford Standard for Citation Of Legal Authorities (OSCOLA), available online and in the library (B.1.l.NOLA) and the Bluebook: A Uniform System of Citation (B.1.l.BLUE).
Reference managers such as RefWorks, EndNote, Mendeley, Zotero and Colwiz can be used to make citing easier and to save and organize references. RefWorks (New, pdf) + (Legacy, pdf), Mendeley and Zotero are supported by the library.
