Introduced earlier this year, the platform incorporates sophisticated but user-friendly features and an extensive, proprietary taxonomy to serve both the occasional user as well as the professional researcher by producing highly relevant results.

Recently enhanced Dialog scientific, technical and medical research services to be spotlighted in London include:

• Beilstein, a renowned collection of organic chemistry research that recently was re-organised and expanded
