You still include these texts in the final bibliography.
Use the School's CiteMaker site to write correct bibliographies and intext references. The site provides you with step-by-step instructions on how to complete a bibliography and you are also able to create an account, allowing you save and export your bibliography.
Remember that there is nothing wrong with referencing lots of different sources, this shows that you have researched widely.
