The BNI database was formed in 1996 with the merging of the Nursing and Midwifery Index database and the Royal College of Nursing’s "Nursing Bibliography". The BNI database was launched on 1 January 1997 and covered 220 journals. , 81 of the journal titles indexed by BNI are not covered by the CINAHL databases, and 51 of these are published in the UK. In 2011 the database was acquired by ProQuest.
