Why are some abstracts in the ADS database different from the published ones?
Some of the abstracts in the ADS database (most abstracts in the time span 1975-1995) were given to us by the STI program at NASA, which in most cases rewrote the abstracts to avoid infringing the publisher’s copyrights, often shortening the author’s original abstract. In general, there is no way to be certain whether an abstract which originated from STI has been rewritten or not. Abstracts that we receive directly from the publishers and the original authors (called “author” abstracts) are instead a faithful and accurate reproduction of text that was published in the paper’s abstract (except for math and non-ASCII symbols, of course). Individuals who wish to submit original abstracts to be included into our system can do so through the Abstract Submission Form (see also previous question).
