What proportion of preprints are replaced by peer reviewed reprints?
Written by Tim Brody, last updated August 31 2000 10:09:20.
Using data from the publication rates.
The proportion of papers that have got Journal-ref entries is 36.87% (see publication rates). The proportion of papers that have had more than one submission is 21.92% (see question two). This means that the maximum proportion of papers that could be submitted as preprints and then submitted as peer-reviewed reprints is 21.92*36.87 = 8.08% (as a proportion of all papers in the archive).
Using year of publication
The date of publication has a granuality of 1 year (i.e. year of publication). It has been stated that the majority of papers take 8 months to be published, from the initial preprint being sent to the publisher. If an author submits the preprint at the same time as sending it to the publisher, and then submits the reviewed print at the same time as publication, this will be indistinguishable from an author who submits only at or after his/her paper has been published. This puts a question mark over whether this question can be answered, when looking at the historical record of abstracts.
From the data available it is possible to say with some certainty that the number of authors who replace preprints with reviewed papers is less than 60%, as 41.68% of published articles have only had submissions before their year of publication.
From anecdotal evidence (see The Typical Life of
a Scientific Paper, quant-ph/9912113), it is apparent that authors may
follow the procedure of:
All within a period of one year (although, in the particular example the "year" went over a New Year, so therefore would feature in the following statistics).
Any submission following or at the date of publication is the reviewed work, and any submission before time of publication is the un-reviewed work.
Number of papers that have been submitted to before and at
Number of papers that have been submitted to before and after
publication (excluding papers that have been submitted to before, at and
Sum = 3392.
If we take the background population of published works as the number of lines in d_publishedcount, 48742 (number of abstracts with matching Journal-ref fields), we can work out the proportion that could be preprints replaced by reviewed reprints:
(3392/48742)*100 = 6.96%
Using Incremental Update Data between Nov 1999 and Jun 2000
This graph is a plot of how many papers had their journal-ref entry added on a particular day since their first submission. This is based on incremental update data from November 1999 to June 2000.
1625 papers that had submissions in the period were initially submitted without a Journal-ref, and then had a Journal-ref added at a later date. The number of papers with submissions in the period was 23974 (with 1 or more submissions being made those papers). 5262 papers had 2 or more submissions.

these 1092 had their 2nd or later submission including a Journal-ref.

Number of updates to abstract that also updated the paper (i.e.
Journal-ref added along with reviewed print):
100*(47/4031) = 1.17% of papers submitted between Nov 1999 and Jun 2000, had a Journal-ref entry added, along with a updated paper, within the period.
This data needs to be over a more extended time period to identify when the highest rate of publications are (existing data suggests that the typical period between initial submission and publication is 8 months).
Paper updates vs Abstract Updates
Using the incremental update data from the six month period and identifying which updates have been made to abstracts and which updates have had a paper submitted with them (when the Journal-ref entry was added).
For the following, the mirror received the first deposit in 1999/12/29 and the first deposit that contained a Journal-ref was on 2000/06/18. No paper was submitted with the abstract update.
