Our free InterLibrary Loan (ILL) is a great way to access articles and chapters that are not available in SOLO. Just fill out the online form and we’ll try and get a copy of what you need from another UK library: https://www.bodleian.ox.ac.uk/services/borrow/inter-library-loans.
For books the items can be ordered to the vere Harmsworth Library (VHL), where the RSL collection is currently located. For journal articles or individual chapters you can be sent an electronic version.
You can make requests until 15 August this year. After that the service will be unavailable for a short time, until 23 August. Still plenty of time to get your orders in.
