A while back, you suggested that I use a mask when dealing with the old dusty and sometimes moldy books. Well, I have been having trouble with my asthma lately(no attacks, just tightness in the lung area.) My allergist and the nurse who is assigned to help you manage my asthma have both advised me that I must wear a mask whenever examining the books.
The last thing the nurse said was something for me to seriously consider. She said, "Maybe this isn't the best place for you to work."
As a sophomore in college, I worked as a library page. I worked at one of the older branches. The place was dusty and moldy. After about 9 months of working there, I decided to get tested for allergies. The results were that I was allergic to all grasses, dust, dust mites, all animals, and all trees. I quit that job and began working various office jobs.
I still like working in the field of libary science, but I will probably seek out something behind the scenes. It is probably time for me to stop dealing with patrons and books on a daily basis.
