The UK web archive aims to preserve for posterity websites with UK domain addresses. It has a number of special themed collections.
The Gender Equality section is subdivided into specialist sub-sections for body, gender identity, pay equality, suffrage, parenting, domestic abuse and equality in the workplace. 290 sites are currently being archived. It is possible to browse the captured snapshots or search by keyword the full text.
Note: some hits can only be viewed under legal deposit rules within the British Library reading rooms.
Most materials date from 2017/18 onwards. This BL blog post describes the project of developing the web archive. It has some interesting statistics on the increasing coverage of gender equality on the web.
