Kent The citation without the name is perfect (and this appears to be how most citation parsers work). There are two issues in the test run:
1. The parallel citation 422 U.S. 490, 499 n. 10, 95 S.Ct. 2197, 2205 n. 10, 45 L.Ed.2d 343 (1975) is resolved as: 422 U.S. 490 (1975) 499 n. 10 (1975) 95 S.Ct. 2197 (1975) 2205 n. 10 (1975) 45 L.Ed.2d 343 (1975) instead of as: 422 U.S. 490, 499 n. 10 (1975) 95 S.Ct. 2197, 2205 n. 10 (1975) 45 L.Ed.2d 343 (1975) ie. parsing the second page references should pick up all alphanumeric chars between the commas. 2. It doesn't parse the last citation ie. 463 U.S. 29, 43, 103 S.Ct. 2856, 2867, 77 L.Ed.2d 443 (1983). I tested it on another sample text and it missed the last citation too. Thanks!

Mumma, 956 F.2d 1508, 1517-18 (9th Cir.1992) A few issues here: S.A. - this is hard, to allow this while filtering out sentences R.J. O'Brien, etc. - Loosening up the rules for the second name can allow these 1517-18 - allow page ranges The name issues are getting to be too much for me. Attached is a PLY version that just pulls out the citation without the name; at one point you indicated that would work for you. Kent
