Description
Select an online or issue publication year.
Bibliographic records connect authors, versions, publication dates and locators through explicit identifiers. Literal comparisons and counts help reconcile those records but do not retrieve publications, authenticate sources or establish the quality or meaning of a citation.
Select an online or issue publication year.
When to use this tool
Use Publication Year Early Online Pair when checking the stated bibliographic record, locator, date or counting convention.
How to use the tool and how it works
- Enter onlineYear, issueYear, preferOnline. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read selectedYear, lagYears. Use the output convention below.
Select an online or issue publication year. selectedYear follows preferOnline, lagYears = issueYear-onlineYear.1

}Limitations and assumptions
- Negative lag is retained; both years are supplied and no publication metadata or bibliometric policy is authenticated.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Inspect the original publications and authoritative metadata, and use complete identifier-aware reference management for scholarly attribution and evidence appraisal.
