We have built up what is probably the largest, most comprehensive collection in the world of unrestricted reports available for public use. Approximately 4.9 million are held in total. Particular strengths are:
- British research and development reports
- Reports distributed by US federal agencies, such as DOD, DOE, ERIC, NASA, NTIS
- Reports distributed by international agencies, such as INIS, ESA, FAO, EU
Many other report series issued in many countries are also held. The report series titles are available free online in the Serials file of Explore the British Library. There is also our bibliographic publications.
