What is a? A sort guide is a guide book printed on cards. Each sort guide consists of a deck of cards, sorting tool and instructions packaged in a durable chipboard box, (so they may also be used in the field or laboratory.)
The cards have a description side showing illustrations and text, and an index side which lets you find the cards you want. No matter what subject your sort guide covers, the index side shows the characteristics you can sort for. Choose a characteristic and run the sorting tool through the hole at that characteristic. The cards that drop out won't have the characteristic you selected. Continue this process until you have eliminated all but one card.
