There are two ways to create a website using OpenScholar:
Go to hwp.harvard.edu and select "Get Your Website" on the homepage. This is the self-service option and it is free.
Contact HWP to choose the "Basic" option. This includes project management, content strategy and other services. The cost depends on your affiliation. You can find more information in the Pricing section of the site.
HWP, part of HUIT's Administrative Technology Services, manages all OpenScholar websites which are hosted on the Acquia cloud. The cost varies from free to $22,000 per year, depending on the service level you require and your Harvard affiliation. You can find more information in the Pricing section of the HWP website.
