1. There has to be a conjunction between "important," and "other" because otherwise, the sentence doesn't seem coherent. You can place 'but' between those words to make it correct, and to connect the two ideas into one sentence. 2. The phrase 'such as journal entries and poetry' should be placed after 'period' because otherwise, it is located too far from the word it is supposed to describe. So, 'fiction from that time period, such as journal entries and poetry, can be just as valuable.' 3. Again, there should be a conjunction between the words 'read' and 'they' because the way this sentence is written, it doesn't seem connected. You can write either '...are interesting to read because they give..." or '...to read as they give...'
