Filing and retrieving a personal collection of 35-mm teaching slides in medicine. A simplified system
Abstract:
The use of 35-mm slides to teach or supplement lectures has become an important technique in medical education. To be effective, the slide collections need an efficient filing and retrieval system. The systems previously described for filing and retrieval of slides usually are expensive, require many materials and much space, and are more suited for slide libraries and large collections than for personal collections of teaching slides. A more simple and inexpensive system to file and retrieve personal collections of 35-mm teaching slides uses color labels to identify groups of topics and also numbers to identify each slide in a given group. The color labels also help in proper loading of slides into the slide tray. This system can be expanded easily to suit individual needs.

Fixation and Sectioning
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
