Access to articles in ACS Publications Online is complicated to describe. The library has subscribed to 15 "Core" titles (listed below). Library access to the "Core" titles is unlimited. ACS has a number of other journals that are outside of our "Core". Access to recent articles outside the "Core" are paid for with "tokens", which we purchase in advance from ACS.

When you conduct a search in ACS, you will see all of their journals, including those that require tokens for access. As a user, you are generally able to seamlessly access both Core titles and titles that require a token. We maintain a token account, and that account is automatically debited when a user accesses a non-Core title. The tokens are only required when someone needs to access an article published from 1996-present in a journal that is not part of our Core Plus Package (the 15 titles below), books or chapters from the ACS Symposium Series (eBooks), or articles from the Chemical & Engineering News Archive.

if all the pre-purchased tokens get spent, we lose access to articles that require tokens until we add more tokens to our account. If you are currently unable to access an article from ACS Publications, contact the Desk and ask to speak with a Research Librarian. 508 565-1313, or
