11. Comparison Suppose you want to look up the word "synecdoche.“ Which of the following scenarios do you prefer? 1. Find volume 10 of the OED and learn that Wyclif (1338) defined it as "whanne a part is set for al, either al is set for oo par..." 2. Start computer, find CD ROM, load CD ROM, go to OED, step through program, find information, unload CD ROM, turn off computer, file CD ROM, go back to what you were doing in the first place. 3. Open W3 and read "a figure of speech by which a part is put for a whole (as fifty sail for fifty ships)..." W3 is THE dictionary. It belongs in everyone's home. At the listed price it is an incredible bargain. Highly recommended
