+##### To concerned organizations

+Probably sponsorship would be best suited from organizations benefiting from having such works being disclosed, published and spread. Usually a specific amount of budget in some organizations, departments,institutes etc. should be spend before the end of the financial year. If there is a confusion how to spend available money, I would appreciate a sponsorship in form of donation that would allow to accelerate the progress of this book, among other initiatives that are in confermance with Open Science initiative.
