MyNCBI allows users to store personal configuration options such as search filters, LinkOut preferences and document delivery providers. After logging into their MyNCBI account, a user can save searches and arrange to receive periodic emails containing updated search results. A MyNCBI feature called ‘Collections’ allows users to save search results and bibliographies indefinitely. Several enhancements have been made to MyNCBI in the past year, particularly regarding sharing information with other users. A new ‘Shared Settings’ panel provides a single interface where a user can select settings to be shared, and then by constructing a simple URL and providing it to other users, the entire group can access these common settings. In MyNCBI, both collections and bibliographies can now be set as either private or public, the latter of which can be shared with multiple users. Finally, the Recent Activity feature has been dramatically expanded to include up to 6 months of activity within MyNCBI, rather than only a user's; previous five actions.
