+## Terms of use
+
+This dataset contains **metadata only** (no full texts or files). Its reuse is governed by the
+*Política de metadatos* of [DIGITAL.CSIC's policies](https://digital.csic.es/dc/politicas/):
+
+- **Non-profit purposes.** DIGITAL.CSIC metadata may be reused without explicit permission for
+  non-profit purposes. Any other use requires permission from CSIC (digital.csic@bib.csic.es).
+- **Link to the original record.** Each reused record must mention its OAI identifier or link to
+  the original record in DIGITAL.CSIC. Every row carries this link in `handle_uri`; keep it in any
+  derived work.
+- Please also cite DIGITAL.CSIC (CSIC) as the source of the metadata.
+- The `license` column is the licence of each deposited work (often a Creative Commons licence),
+  not a licence for its metadata. Full texts are subject to DIGITAL.CSIC's separate data policy
+  (systematic harvesting of full texts requires explicit authorization from CSIC).
+
+## Personal data
+
+Records contain names of researchers and, where available, ORCID iDs and DIGITAL.CSIC researcher
+profile ids. No e-mail addresses or other contact details are extracted into the columns above.
+Withdrawn or deleted items are removed when the dataset is refreshed. Requests to remove personal
+data from DIGITAL.CSIC go to digital.csic@bib.csic.es; please also open a discussion on this
+dataset so the copy here can be updated.
