NIH staff should first check the column in the resource display labeled "userid/password" to see if there are any special instructions that you need to follow.
Non-NIH users will not see information in that column as publisher licenses restrict us to offering electronic resources to NIH staff only.
If you still need help, call the NIH Library's helpline at 301-496-1080 or submit your question online. Library staff will reply within one business day.
