The library has subscribed to two services that will help you to find open access articles, as well as those subscribed to by the library.
LibKey Nomad is a browser extension that will connect you to full-text articles that are either available via a University of Bristol Library subscription or open access. Read more on the Library webpages.
LibKey.io allows you to access journal articles which are available either by library subscription or open access, by using either a digital object identifier (DOI) or a PubMed identifier (PMID). More information is on the Library webpages.
