If you are looking for any articles on a particular topic...
For a wide-ranging literature search, Westlaw UK has the largest coverage; Lexis®Library is the other main source for UK articles.
Westlaw UK aims to index every substantive legal journal article published in the UK since 1986; it also covers English-language journals published on the Continent. It has full-text articles from about ten per cent of these journals and abstracts from the rest, covering more than 1,000 journals altogether. The main focus is on UK law (EU, foreign and international law are also covered).
Lexis®Library's Journals Index Plus goes back to 1995 and covers over 500 journals and blogs, most of them published in the UK; more than 120 of the journals are available in full. The main focus is on UK law (EU, foreign and international law are also covered).
There is some overlap between the full-text journal collections on Westlaw UK and Lexis®Library, but many journals are only available in full-text form on one or the other: for example New Law Journal is on Lexis (1987 onwards), but Westlaw has abstracts only; Law Quarterly Review is on Westlaw (1986 onwards), but Lexis has abstracts only.
For interdisciplinary journal research, see EBSCOhost and JSTOR, which cover thousands of journals on a wide range of subjects, published in the UK and elsewhere (either full-text or indexed/abstracted); both are available via the IALS Electronic Law Library,
If you are looking for a specific journal article...
Start with the IALS Library Catalogue (not the Electronic Law Library). Do a Title search for the name of the journal (not the article), for example, Modern Law Review. If the journal is available online at IALS, there is usually a link on the catalogue record (however, not all the journals on Lexis®Library currently have links from the Catalogue).
