Since I moved to Somerville a few years ago, I was amazed at the lack of a bookstore in the area! I was so relieved that we finally got one and it's in a perfect spot. I often stop by for a quick browse when I'm doing my shopping at the supermarket. The staff is very friendly and always accomodating. Just today one of my co-workers visited Porter Square Books for our latest bookclub book. They had ordered a few copies for her because they were out of the book that we are reading.
I really hope that they can continue on this track of success. I feel like the opening of the cafe within the bookstore will help out business as well. I would love to see more bookmarks there (I was looking and couldn't find any) but overall, I think that this is a great addition to the area.
