Blackwell Synergy content was incorporated into Wiley InterScience and the Blackwell product will be discontinued. As the transfer is finalized there may be intermittent periods without access.
Access to Blackwell links on the A-Z journal title list and via the SFX "Get Text" button will go to the Wiley InterScience home page, not directly to the journal title. Wiley is working on getting links to go directly to each journal.
They estimate it will take a few days. In the meantime, the articles are there but you have to navigate to the journal to get them.
To find a journal from the Wiley InterScience home page:
Use the Search Box with "Publication Titles" selected
Click journals under "Browse by product type"
Use the Title or Subject option to find the journal
