Read the passage. with my backpack full of notes about my essay and borrowed books, i trudged through the slush to the library. after months of note-taking, i was eager to compose my thesis. the library’s fourth floor housed a computer lab, and i could hear the hum of fifty computers as i exited the elevator. unfortunately, there were no available computers, and among the political posters on the wall, a makeshift list had been added for people awaiting a turn at a computer. i added my name to the list and considered returning to the typewriter in my dorm room. what can readers infer about the time period of the passage? textbooks were too expensive for students to afford. college students were expected to publish their writing. college libraries were gathering places for student activists. personal computers were not the norm among students
