TAB-IT® Indexing Systems' patented tabs are the original tabbing system for use with the DSM. Designed in 1995 by psychology graduate students, they were recognized as a national leader for design and function by Business, Forms, Labels and Systems magazine. The TAB-IT® System for the DSM-5-TR includes 75 laminated tabs and an installation template. Tabs have a patented color arrangement for easy identification of major sections. There are also three white TABLE tabs marking critical diagnostic tables. Each tab has the diagnosis scripted on it, and is easily applied using the installation template. No cutting, punching, or writing - just peel and stick! Once applied, the tabs are permanent and so strong you can literally hold the book up by a tab.
