Articles that are published using an Open Access model are available to be freely read by anyone, whether immediately or after an embargo period. Often, instead of the journal being funded by its subscribers, it is funded by authors paying fees to have their articles published. This is an option you may want to look into as you decide in which journals to publish.
Detailed information on Open Access, including advice on where to seek financial support for author's fees, is available on the UH Libraries' website.
