An introduction to IALS Library's electronic resources.

Journals and books


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).

Cases and legislation


Westlaw UK and Lexis®Library both have UK law reports from 1220 onwards, with case citators for updating purposes. The Law Reports (the leading UK series, published by ICLR) and some other series are on both Westlaw and Lexis, but for the most part the collections do not overlap: for example, only Lexis has the All England Law Reports, Commercial Law Cases is on Westlaw but not on Lexis.

Westlaw has unreported cases from 1967 onwards; Lexis has them from 1980 onwards.

Scotland and Northern Ireland
Westlaw has numerous Scottish law reports, including Session Cases, Scots Law Times, Scottish Civil Law Reports and Scottish Criminal Case Reports; Scottish cases are included in Westlaw's Transcripts collection. Lexis has Session Cases, Scottish Civil Law Reports and Scottish Criminal Case Reports, plus a collection of transcripts called Scottish Court Opinions.

Lexis has the Northern Ireland Law Reports, Northern Ireland Judgments Bulletin and a collection of transcripts, Northern Ireland Unreported Judgments. Westlaw has Northern Ireland judgments in its Transcripts collection.

*Northern Ireland Orders in Council are Northern Ireland statutes published in the form of UK statutory instruments. The official HMSO / TSO versions have numbers prefixed with 'NI' as well as SI numbers, but the Westlaw versions omit the NI numbers. 

Justis has the original text of acts of the Northern Ireland Assembly from 2000 onwards and the original text of Northern Ireland Orders in Council (in the Statutory Instruments database) from about 1987 onwards. 

Many, but not all, pre-1987 Northern Ireland Orders in Council are on the official website

Secondary legislation

UK statutory instruments (SIs)

Lexis has all SIs in force for England and Wales, as amended; it does not have SIs applying only to Scotland. Westlaw has all UK SIs from 1992 onwards and a large selection of older SIs, as amended. Westlaw includes UK SIs applying only to Scotland, but Lexis does not.

Justis has the original text of UK SIs from 1949 onwards. It also has pre-1949 SIs which were still in force on 31 December 1948 (from the 1948 HMSO revised edition). Justis includes UK SIs applying only to Scotland. 

Scottish statutory instruments (SSIs) 
SSIs are post-devolution Scottish secondary legislation. Westlaw and Lexis have them as amended and
Justis has them as originally made.

Welsh statutory instruments
These are statutory instruments made by the Welsh authorities since devolution; they have reference numbers prefixed 'W.' as well as SI numbers, for example, 2017 No. 1274 (W. 296). Lexis and Westlaw both have English-language statutory instruments for Wales, as amended, and Justis has them in their original versions.
