The Bodleian Social Science Library is the principal library for taught course provision for politics & international relations, along with new research material, contemporary works (including legal deposit), and the core journal collections in politics, international relations and related subjects. Fortunately it is the Law Bod's immediate neighbour if SOLO tells you that it has books that you would like to consult!
To subject search SOLO try one or more of the following (in some aspects there is much inter- or cross-disciplinary interest)
constitutional law - economic aspects
constitutional law - social aspects
separation of powers
rule of law
Legitimacy of governments
theory of justice
Law -- Political aspects
Public law -- Political aspects
To these you could add the name of a jurisdiction (eg France) to reflect your particular interest.
To find series (such as Constitutional systems of the world) set the search filters to exact phrase + anywhere in the record.
You don't need to do anything special to find e-books - SOLO should find them along with printed copies. E-books have a View Online link to click; print items have Find & Request link to click to find the Call number/Shelf Mark.
The online guide below could help with how best to search SOLO
The current monographs about constitutional law from the UK (& all constituent jurisdictions), Australia, Canada, Ireland, New Zealand and USA have been arranged according to the Moys Classification Scheme. A table below shows how Moys shelfmarks begin for some topics.
The works on English & Welsh/UK law are shelved first. Then works on the treatment of the law by the other jurisdictions follow, country by country. In these cases, the third line of the shelf mark indicates which "foreign" jurisdiction the work is concerned with - using the following codes - A8 Australia, C1 Canada, Ireland I5, N4 New Zealand, S3 Scotland, U4 United States.
