From the ISCB website:

...Our emphasis is on the role of computing and informatics in advancing molecular biology. The Society serves its membership by facilitating scientific communication through meetings, tutorials, publications and by electronic means; by collecting and distributing information about training, education, and employment in the field; and by increasing the understanding of the significance of our endeavor in the larger scientific community and in the public at large.
