• Special Characters: Unicode support for accents and special characters may vary by output format
• Edition Numbers: Different styles format editions differently (ordinal vs text)
• Author Name Formats: Input should be "Last, First" format; parsing other formats may be inconsistent

• Online-First Articles: Articles published online before print may have partial metadata
• Non-English Sources: Some citation styles have specific rules for non-English sources that may not be fully implemented
