Though the first letter is a lot of pressure, I have chosen you to start with because you're at the top of my mind. I must mention that despite writing to you first, my letters will be in no particular order; I do not appreciate your organization and services more than I do, say, my family. It's just that I was thinking of you and it seemed as good a time as any to express my appreciation.
Thank you for your services. Thank you for being convenient, both in location as well as offering so many books for digital checkout. You have saved me hundreds of dollars both in book costs as well as gas, and so many measures of frustration and probably quite a few hours, too. Being able to go online to request a book, to download it, and loading ebooks onto my Nook or audiobooks onto my iPod, for free, is amazing. Not having to go to the actual library is a bonus, as it allows me to spend my already limited time reading the books you offer, not running annoying errands to pick up or return (or keep track of) your tomes. You have given me the ability to do more of what I like (reading) and less of what I don't (driving unnecessarily). This is invaluable to a grad student whose recreational time is relatively nonexistent, so thank you. I am grateful that you exist.
