||Certain titles such as the drug databases may be updated on a monthly or quarterly basis (depending upon the publisher's schedule), whereas other clinical titles based on the popular print edition are updated on an annual schedule (or sometimes even more than a year). For such clinical print titles, there may be some minor data "corrections" provided by the publisher. Skyscape releases the updates of the titles in such cases. In addition, Skyscape frequently introduces software enhancements to our product line to serve the needs of our user community. Updates are made available at such times as well.
