I am often asked about open access and particularly about the difference between the green and gold models. While the aim of open access is to make freely available on the internet research articles and books for widespread use, the publishing models behind it are a little complicated.
We all know why access to scholarly research is so important:
“If I have seen further it is by standing on the shoulders of giants” (Newton)
What are the advantages of Open Access?
- Global access
- Global availability
- Global exposure
- Increased citations and usage
- Faster innovation
What is green open access?
Researchers can deposit a version of their published work into a subject-based or institutional repository.
What is gold open access?
Researchers can publish in an open access journal and the publisher provides free online access. The Directory of Open Access Journals (DOAJ) is where to find such journals.
There are various business models behind Open Access.

|Gold||For profit||Author by fee|
|Gold||Hybrid gold, for profit||Author by fee +library by subscription|
