At the end of October 2023, the British Library was subject to a major cyber-attack, which disrupted access to electronic Legal Deposit (eLD) content. A large-scale exercise was subsequently undertaken to check the integrity of the vast core eLD dataset. This led to the development of a new secure interface for accessing eLD content collected prior to October 2023 (excluding the UK Web Archive, which remains unavailable).
The ELD SOLO Browser is an interim solution with reasonable functionality for searching, citation, and printing. Use this guide to make the most of navigating and using eLD content.

Under the current 2013 Regulations:
How is this material collected and stored?
Items deposited under electronic Legal Deposit (eLD) are collected from publishers or self-submitted via an online portal and then processed at the British Library. The digital objects themselves (e.g. PDFs for journal articles, ebooks in epub format etc) are stored on specially-commissioned servers at the British Library datacentres in London and Yorkshire and replicated to similar nodes at the National Libraries of Scotland and Wales. Metadata (i.e. catalogue records) for the ingested items is then made available to the Legal Deposit Libraries to be incorporated and indexed in their local discovery services.
