Germ wiki:
>For other senses of the word "germ", see germ (disambiguation). Germ is an informal term for a disease-causing organism, particularly bacteria (as in germ warfare). One of the first people to postulate that some diseases were caused by the presence of some kind of very small 'seed' (the original meaning of 'germ') that germinated or multiplied in the body to produce the disease was Ignaz Semmelweis, a Hungarian doctor, practising in an obstetrics ward in the 1840s. He noticed that the death rate of the impoverished women attended by the nurse midwives was many times less than that of the wealthier women attended by the doctors. His observations led him to conclude that it was a matter of cleanliness. The doctors, on their schedules, went directly from the morgue to the obstetrics ward without washing their hands. When he presented his findings to fellow doctors, they discounted his theory, unable to believe in what they could not see. It wasn't until the 1880s and the work of Louis Pasteur and Joseph Lister that the truth of germs finally surfaced and was accepted by the scientific community.

Clip art wiki:
ip art, in the graphic arts, is the use of images either copied or physically cut (hence the term) from pre-existing printed works, either books that have entered the public domain, or books specifically published for such use (which, if they contain images that are not in the public domain, include a license fee in the cover price). It is also not uncommon for large organizations to provide their local divisions or chapters with clip art (either physical or electronic) of their logos, mascots, and so forth, in order that local publications may have a unified appearance. It is also rather common for those producing documents with limited distribution to use images from non-public-domain sources for which they have not paid license fees, such as coloring books, newspapers, magazines, and such, although some magazines, particularly those dealing with hobbies will publish images explicitly licensed to the magazine purchaser for use as clip art.
