It is open access week, a time to consider the free and open sharing of scholarly information. Many people are familiar with sharing journal articles but have you considered sharing your posters? It can take a lot of time and effort to produce a poster for a conference for only a few people to notice it. If you are working in biomedicine F1000 posters provides a site to share your posters – it is free to view and deposit.
If you are working in other fields Figshare will also accept posters and gives a doi so that you can easily share and cite the link to your work.
