Using first person in literature recommendations in a masters thesis?
Unless there is some reason to specifically avoid it (e.g., your have an advisor who absolutely won't tolerate it), feel free to use the first person and "I" statements in lieu of traditional academic language like "the author" or a strict adherence to the passive voice. Your readers presumably already know you are the author. Anything you can do to improve their comprehension of your work is worth doing. Plus, as this editorial in Nature suggests, "Personal language builds a connection to the reader and helps, ultimately, to persuade".

As for the literature suggestions, a separate section for providing some brief background explanations may be helpful. You can use such a section to include context along with references to the further reading.
