Index to Legal Periodicals

The Index to Legal Periodicals is an indexing database, containing bibliographic details of over 1,000 journals (877 excluding name changes), published in the US or UK, and concerning the Anglo-American legal system. Some titles from Canada, Australia and New Zealand are also covered. Whilst the database does not provide full-text access to any of the periodicals or articles, it is an invaluable source for performing a comprehensive search to see exactly what is available in terms of journal articles on particular subjects. Used in conjunction with other IALS Library electronic resources such as Hein Online, and our extensive hard copy holdings, ILP can be a valuable research resource. ILP also includes details of new books.


ILP is available to all library users onsite at IALS, and to School of Advanced Study students and teachers offsite via controlled password access. In both cases, the access point is through the Electronic Law Library from our website.


ILP provides a fairly detailed citation to each legal article written within all of the 877 journal titles it indexes, including titles which have ceased publication. The list of these titles, known as the Journal Directory, is available from the homepage, including details of indexing start and end dates. This list is maintained and updated on a regular basis.


You can search at a basic or an advanced level. The basic search offers just a free text box to search by words or phrases in the database. This is a useful search if you are just getting started in your research, but may well return far too may results to be of much use. The advanced search allows greater flexibility, with 3 text boxes which can be combined with Boolean (AND, OR, NOT) operators, limiting the term to search for a variety of options such as subject, word in title, author, cases mentioned and even Dewey Decimal classification number. Searches can also be limited by date and material type.

Help Files

There are very detailed help files available within the database, on the homepage and on the search screens. These files include information on basic and advanced searching, browsing and customising your results, printing and saving options, Boolean operators and a number of other functions. There is also a tutorial option available for novices who wish to practice searching.
