Open access: Glossary

APC (Article Processing Charge) = open access fee, publication fee, author fee - fee that some journals require to make an article OA 

BPC (Book Processing Charge) = open access fee, publication fee to make a book OA

Creative Commons (CC) license - copyright license applied to a work, defining how it can be used (e.g., shared, copied, modified, sold). 

Diamond open access - free full OA (all articles in a journal are published openly without APC fees). Free for both readers and writers 

DOI (Digital object identifier) - permanent identification number (link) for electronic documents, e.g., an article in a journal 

Embargo - a publisher's restriction on how soon after publication an article can be made available in open archives and on websites 

(Full) open access - publishing form where all articles in a journal are openly available (some full OA publication channels require APC fees)

Gold open access - typically used synonymously with full open access, see full open access 

Green open access = parallel publishing, self-archiving - a version of an article that is primarily published elsewhere is uploaded to an open archive or repository (e.g., the university's own parallel publishing channel) 

Hybrid open access - publishing form where an article in a subscription journal is published OA as a fee-based additional service (APC). Therefore, only a part of the articles in the journal are openly available and the rest behind a paywall. 

Open access (OA) - research results are made freely available in digital form (a publishing/business model and an ideal) 

Parallel publishing/self-archiving - see green open access

Postprint = (author’s) accepted manuscript (AM/AAM) - the peer-reviewed version of an article, with any reviewer suggestions incorporated (usually lacking the publisher's layout details)

Predatory journal - publication channel with poor quality that acts unethically and primarily strives for financial gain

Preprint = submitted version - the version of an article that has been submitted but not yet peer-reviewed

Publisher's PDF = final PDF, version of record (VoR) - the final published version of an article 

Read and publish agreements - Agreements for journal packages that allow researchers at universities to publish OA (both full and hybrid OA) at a discount or for free in several of the publishers' journals. The agreements also include access to read closed subscription journals. FinELib is the national negotiating body for the agreements.
