How to calculate H-Indexfor research publications. Author: John P Itteera.
Ex:Publication report as given by Faculty "A"

Publication year Publication serial No. No. of Citations.
2001 1 15
2002 2 2
2002 3 11
2003 4 7
2004 5 7
2004 6 8
2005 7 11
2006 8 1
2007 9 4
2008 10 5
2009 11 6
2010 12 9
Total   86

Now you arrange the table in descending order for the column "No. of Citations"without columns "publication year" and "Publication serial No." and add a new first column with serial number for indexing starting from 1.

1 15
2 11
3 11
4 9
5 8
6 7
7 7
8 6
9 5
10 4
11 2
12 1

Comparing "column 1" and "column 2" till "column 2" number is not lesser than "column 1" as in 7th row. Ex:-
Value in 1st row of "column 2" is greater than corresponding value in 1st row of "column 1"asvalue 15>1
Value in 2nd row of "column 2" is greater than corresponding value in 2nd row of"column 1"asvalue 11>2
Value in 3rd row of "column 2" is greater than corresponding value in 3rd row of "column 1"asvalue 11>3
Value in 4th row of "column 2" is greater than corresponding value in 4th row of "column 1" as value 9>4
Value in 5th row of "column 2" is greater than corresponding value in 5th row of"column 1" as value 8>5
Value in 6th row of "column 2" is greater than corresponding value in 6th row of "column 1" as value 7>6
Value in 7th row of "column 2" is equal to corresponding 7th row of "column 1" as value 7=7
Value in 8th row of "column 2" is less than corresponding value in 8th row of "column 1" as value 6< 8
Value in 9th row of "column 2" is less than corresponding value in 9th row of "column 1" as value 5<9
Value in 10th row of "column 2" is less than corresponding value in 10th row of "column 1" as value 4<10
Value in 11th row of "column 2" is less than corresponding value in 11th row of "column 1" as value 2< 11
Value in 12th row of "column 2" is less than corresponding value in 12th row of "column 1" as value 1< 12th

Now since value is 7th row of "column 2" is equal to corresponding value in 7th row of "column1" we consider the H-index of "A" is 7
Imagine a second scenario where value in 7th row of "column 2" is 8 and the remaining value remains same in the table, still value of H-index of "A" will remain as 7 as the value in "column 2" of subsequent row is lesser than the corresponding value in "column-1" for that row.(in this case 8)
