Introduction to the Library Catalogue

This Subject Guide only lists a selection of Library resources on the Law of Treaties. To find additional resources you will need to search the Library Catalogue, which covers the complete holdings of the Library. It is possible to search for books, journals and series of law reports by author, title or keyword. Please note it is not possible to search for individual chapters, journal articles or legislation (e.g. individual Acts or SIs).

IALS Library is mainly open access and readers are able to browse the shelves in the main collection. There are two main exceptions to this:

  • Older items (marked RES or Depository on the catalogue record) are kept in the closed basement.
  • Key texts for LLM students are often kept in the Short Loan collection.

Please request these at the Library Enquiry Desk.

For more information on understanding the catalogue record and further guidance on the location of materials please refer to our guide Classmarks and the Location of Resources in the Library.


The Library classifies textbooks either by jurisdiction (GO13, GA2 etc.) or according to subject area, examples of which include Comparative Law (SB), Public International Law (SG) and Private International Law/ Conflict of Laws (SH). Textbooks on Common Law topics for Common Law jurisdictions (Australia, Canada, New Zealand, UK, USA) are shelved in a special section (SJ). All classmark sections have a FOL section for oversize volumes, which is located on the same floor of the Library.

When you are searching the Library Catalogue for books, please note that only the current edition is held on the open shelves or in the Short Loan collection. IALS has a rich collection of previous editions held in the closed basement and these will display a Depository number on the catalogue. Please request previous editions from the Library Enquiry Desk. 

Treaties and Law of Treaties material is shelved at SG35 and SG40.

The following list represents a selection of textbooks on Law of Treaties. Please check the catalogue records for further information and location. Titles marked as e-books may also be available in print. Access from home requires your IALS library barcode and your  family name.  E books with 'open access' status on the catalogue are available to all users of this guide.
