EndNote is a program which lets you store, manage and search for references in your own database. References from your database can be inserted into a Word document and the bibliography automatically compiled by EndNote. References from online databases like Web of Science can be copied into EndNote without retyping. There is also an online version of EndNote.
For full help on using EndNote, check out the EndNote Library Guide.
OSCOLA is rarely covered well by reference management software but it can help you keep track of your research.
