The binder should never contain more than two indexes, one ivory and one green . Digest is a detailed, objective and timely weekly distillation of the news and current information as reported in more than 70 major newspapers and news magazines from the U.S. and around the world. It is updated weekly and filed in a large blue binder behind the desk . File each weekly News Digest in the binder immediately behind the preceding issue, so the page numbers run in sequence. The Facts on File Index is published twice monthly.
Blue indexes cover information published during the most recent quarter.
Each blue index replaces the previous blue index. At the end of each quarter, all indexing up to that point is compiled in a yellow index. Each yellow index replaces all prior blue and yellow indexes. Check the box on the front of each page for filing instructions. A downward pull on the slide bar at the back unlocks all three posts simultaneously, and the back cover swings clear of the posts.
