Some journals have an impact factor, which is the ratio of citations to papers over the previous two calendar years. One way to think of this number is 'average citations per paper for this journal.' Enter the minimum desired score (usually between 1 and 10).

Enter search terms separated by and or or (but not both). For example:

Exact term search:

lung and carcinoma

Use quotes to search phrase:

"high correlation"

Use * for wildcard:

kras* or *ib

Use tilde (~) for fuzzy matching (can be slow):

~color
