Ismaila Badmus There are several ways to get funds to pay the expense of publishing a chapter contribution in an open-access magazine. Applying for financing through your university or department is one possibility, since they may have grants or cash available for this reason. Another possibility is to seek financing from professional organizations or associations in your field of study. You might also explore financing from government agencies or non-profit groups that encourage open-access publication. It is also possible to contact the publisher and enquire about potential charge exemptions or discounts.

Do your best and use your own money to make the sacrifice. You won't regret it later :)
